Which do shangwai Jingxiao and Jing'an second center go to

1. The early ecation of infants should start from birth. Infant period is the fastest development of children's nervous system and the most critical period for the development of various potentials. Therefore, the earlier the ecation, the better for children. If conditions permit, parents can choose formal early ecation institutions to conct systematic and comprehensive early ecation for their children. Usually, the reception range of the early ecation center is from six months to three years old, and the best stage is about one year old. Win at the starting point, it is suggested that the baby should be about 1 year old and start to read early ecation
win at the starting point ability early ecation is more professional in early ecation. Take win at the starting point teaching as an example, the i4ce teaching system independently developed by win at the starting point includes 12000 + multi page game scenes, 6000 kinds of parent-child interactive teaching games, 3000 kinds of teaching toys and 500 kinds of physical teaching aids. We should adhere to the concept of "giving children the ability to carry, not the schoolbag that they can't carry". We should pay attention to the direct teaching between people and the world. What we do is to spend time and temperature on early ecation. I hope my answer can help you!

2. In the previous stage, the data of JD Vientiane was called once, and the overall accuracy is very high, and the call speed is relatively fast
after all, it's JD, and the amount of API interface data is still very large.

5. No, just jellyfish, which means jellyfish or jellyfish
jellyfish (English Name: jellyfish): it is an important plankton in the aquatic environment, belonging to the class stylospora. Jellyfish is a very beautiful aquatic animal. Its body shape is like a transparent umbrella. The diameter of the umbrella body varies from big to small. The diameter of the umbrella body of the big jellyfish can reach 2 meters. There are some whisker like tentacles on the edge of umbelliform body, some tentacles can be as long as 20-30 meters
the main component of jellyfish body is water, which is composed of inner and outer germ layers. There is a thick mesoderm between the two layers, which is not only transparent, but also floating. When they are in motion, they use the internal water jet reflection to move forward. From a distance, they are like a round umbrella floating rapidly in the water; Some jellyfish umbrella body also has various color patterns, in the blue ocean, these swimming jellyfish with different colors are very beautiful
they can be found in tropical waters, temperate waters, shallow waters, oceans about 100 meters deep, and even freshwater areas. Jellyfish existed 650 million years ago, even before dinosaurs. There are more than 250 species of jellyfish in the waters of the world, which are distributed in the waters all over the world. All live in the ocean
jellyfish is a kind of lower invertebrate zooplankton and carnivore, which belongs to the phylum cnidiidae and the class procephalus in taxonomy. There are about 250 known species. In a broad sense, jellyfish also refers to jellyfish like (bell shaped or dish shaped) cnidia, such as Hydra, Siphonophora, Deming jellyfish (including Sangha jellyfish) and Ctenopharyngodon and thallus, which do not belong to the class dipyridae. There are two types of jellyfish in this class: free swimming jellyfish and sessile jellyfish. The polyp like species living in a fixed environment constitute the order stauromesae
jellyfish appeared earlier than dinosaurs, which can be traced back to 650 million years ago. There are many kinds of jellyfish in different shapes, ranging in diameter from 10 cm to 100 cm, which are common in the oceans all over the world. The vast majority of marine procts, only a small number of species are proced in fresh water, with the most abundant in the shallow waters of tropical and subtropical oceans. Smaller species can be used as fish t; Jellyfish salted into food, some species can be used as medicine; Some planktonic jellyfish can be used as current indicator; However, some large jellyfish (such as nepheline jellyfish, root mouth jellyfish) will block or damage the fishing net when they appear in large numbers. A few species are freshwater, most of them are marine, most of them are in shallow sea, a few are deep sea
jellyfish usually live in a single body, floating or swimming life, and a few species live in groups, some of which can live in a fixed life. The jellyfish body is bell shaped or inverted bowl shaped, or umbrella shaped. The protruding side is called exoumbrella or upper umbrella, and the concave side is called subumbrella. There is a drooping tube in the center of the lower umbrella called manubrium. The free end of the drooping lip is mouth, and the edge of the umbrella has a circle of tentacles, A narrow membranous structure, called velum, protrudes from the edge of the parachute, which is characteristic of Hydra. All jellyfish in the genus Dipterocarpus have no membrane. The structure of the body wall of jellyfish type is similar to that of Hydra type, which is also composed of two layers of epithelial muscle cells with a mesothelium between them, but the mesothelium of jellyfish type is far more developed than that of Hydra type. The gastric circulatory cavity surrounded by the body wall is also more developed. It is either a simple sac or a capsule divided into four stomachpouchs. From the gastric sac, four or more radialcanals (Hydromesae) or more radialcanals (mesae) extend to the fimbria margin, and are connected with the circular canals parallel to the fimbria margin. From the circular canals, centrifugal canals can also extend into the tentacles, All the way to the end of the tentacle. There are sensory organs, such as eyespot or statocyst, at the margin of umbrella or at the base of tentacle
the main stages of life cycle are monosomic and jellyfish type, and the Hydra type is underdeveloped or completely disappeared. The differences are as follows: the size of the jellyfish is generally large, and there is no limbal membrane; The gastric circulation cavity is complex, the radiation tube is well developed, there are endoderm originated gastric filaments, and there are spiny cells on the gastric filaments; There are cells and fibers originated from ectoderm in mesoderm; The germ cells originated from endoderm, and the Hydromesae all originated from ectoderm; There are 4-8 sensory organs
most jellyfish have four radially symmetrical radials, tentacles and senses. Tentacles are one of the most important structures in cnidae, although some Hydra and jellyfish lack tentacles. Tentacles can be divided into two types: one is capitate, short and small, with prickle cells concentrated at the end of the tentacle, forming a cap like structure; the other is filiform, slender, with prickle cells distributed in a ring or tumor shape along the whole length of the tentacle. These two types of tentacles either exist alone in different species, or exist at the same time. The number, structure and arrangement of the tentacles are different in different species. The tentacles are either hollow e to the extension of the gastric cavity, or solid e to the filling of the gastric cavity cells. The number of tentacles often increases with the age of animals, and the base of tentacles often expands, which is the result of the concentration of sensory cells or prickle cells
all seafood. Generation alternation, but the Hydra type degenerated or absent, and the jellyfish type was dominant. Single, mostly large jellyfish, thick gel layer, complex structure. The nerve sense organ is more developed, with tentacle sac, eye point, balance stone, olfactory fossa and other structures, with photosensitive, balance, chemoreceptor and other functions. The absence of membrane is the main difference between the two species. The stomach filaments originated from endoderm have spiny cells, so both endoderm and ectoderm have spiny cells. Gonads originate from endoderm
different jellyfish have different shapes. The main component of jellyfish body is water. The water content in jellyfish body is generally more than 98%, and it is composed of inner and outer germ layers. There is a thick mesoderm between the two layers, which is not only transparent but also floating. Others are made of protein and lipids, so the jellyfish's body is transparent. They don't have a heart, blood, gills and bones. The umbelliform body of common jellyfish is not very big, only 20-30 cm long. When they are in motion, they use the internal water jet reflection to move forward, just like a round umbrella drifting rapidly in the water
there is a special gland in the umbelliform body of jellyfish, which can emit carbon monoxide and make the umbelliform body expand. There is a small ball on the small handle in the middle of the jellyfish tentacle, in which there is a small listening stone, which is the "ear" of the jellyfish. The infrasonic waves generated by the friction between the waves and the air impact on the hearing stones, stimulating the peripheral nerve receptors, so that the jellyfish can get information more than ten hours before the storm, and all of a sudden disappear from the sea
some jellyfish not only vary in color, but also glow in the water. Some of them shine with faint light green or blue purple light, and some of them have rainbow like halos. When they swim in the sea, they become a dazzling ball. Jellyfish glow by a wonderful protein called iquimin, which emits strong blue light when mixed with calcium ions. The more the amount of equiquine in the jellyfish, the stronger the light. Each jellyfish contains only 50 micrograms on average
scientists have simulated the acoustic transmitting organs of jellyfish and found that they can detect the information of ocean storms 15 hours ago. Jellyfish are common in the oceans all over the world. They are a kind of lower coelenterates. They are classified according to the different umbelliform bodies: some umbelliform bodies are silvery, which are called silver jellyfish; Some umbrella shaped bodies are like hats of monks, which are called hat jellyfish; Some umbrellas are like white sails on a ship, called sail jellyfish; Some are like umbrellas, called umbrella jellyfish; Some umbrellas sparkle with the glow of rosy clouds, which are called nephew jellyfish
in stressed closed syllables, the vowel letter e usually pronounces a short vowel / &/ When pronouncing, the tip of the tongue is close to the lower teeth, the front part of the tongue is raised, the tongue position is moderate, does not touch the upper jaw, has no friction, the gums are between half closed and half open, and the lip shape is flat. This sound appears at the beginning and end of the word, but rarely at the end of the word, such as:
egg
well
Red
pen
hen hen hen net
bed
bell

7. When I wanted to buy data, I had a chat with their customer service. According to the customer service, the data source of JD Vientiane is mainly divided into three parts:
the first part is the third-party data, which is provided by some big data procers on the platform; Similar to the supplier model of Jingdong Mall
in the second part, the internal data of Jingdong (Jingdong finance and Jingdong cloud), the non sensitive data generated ring the operation of Jingdong group, are opened to the outside world
the third part, partner data. It is said that there are some large primary data source enterprises, but their customer service did not disclose
the above is for reference. If you want to buy it, you'd better go shopping and evaluate it.

8. The short message platform connected to JD Vientiane is very real, realizing the docking with the platform and the information audit free, so that you can receive the test; Some of them only realize the docking of technical interfaces, but only go through the dead channel or add information audit, so you will not receive the SMS to be tested. I also have the verification code of JD Vientiane, which is open to customers and can be tested, and the information of financial management is subject to audit, However, our audit colleagues see that there is no sensitive content or illegal content in the information, which is generally distributed to test users
I hope my answer can help you. If you are not clear, you can communicate with Babu by SMS.

9. The API interface of tianyanshuju can test the effect first

10. In fact, there is no charge! What data do you buy?
