meinian health examination is reliable meinian grand health provides health examination, health management, health consultation and other services, and has outstanding influence in the medical and grand health sector. It has won "China's best corporate citizen, best social feedback Award", "2018 corporate social responsibility Contribution Award" and other honors

There are three differences between meinian physical examination and hospital physical examination:

1. Medical examination population is different

1. Hospital: a place where patients gather. It is mainly responsible for the examination and diagnosis and treatment of patients and people suspected of having diseases. When they go to the hospital for physical examination, it is difficult to share the examination instruments and equipment with patients, It is inevitable that there will be a potential threat of cross infection e to disease aggregation

2. Meinian: as a health examination institution, the physical examination crowd is mainly healthy / sub-health, compared with the hospital, the health examination equipment is almost not shared with the patients, and the iatrogenic infection is eliminated

Second, the environment and atmosphere are different.

1. Hospitals are built for patients and patients. They are divided according to outpatient service, department and function. During physical examination, they have to go upstairs and downstairs, or even run from one building to another. Nurses are very busy and have no time to guide them. It is too time-consuming for a physical examination

2. Meinian: it is built for the convenience of physical examination customers. It scientifically divides the physical examination areas, implements the separate examination of men and women, implements the efficient one-stop service process, and the design of humanized corridor ensures the smooth passage, and each department and passage has the guidance and diversion of inspection nurses, which greatly saves time and facilitates the physical examination of customers

3. Different service experience

1. Hospital: when you go to the hospital for physical examination, you smell the smell of disinfectant and look at the patients and family members who come and go. Even if you don't get sick, you will feel depressed for a few days when you see the injured people

2. Meinian: it's not because of illness, but to prevent it, nip it in the bud and save the cost of treatment

without comparison, there is no harm. It costs 2000 + to go to the hospital just to have a gastros. However, meinian health has launched a variety of packages with high cost performance, which are definitely the first choice for elderly uncles and aunts

7. Virtual currency does not belong to electronic currency. There's a bit of a similarity.

Virtual currency, from the beginning of q-coin game currency to the present bitcoin, bcbot and other digital currencies, belongs to virtual currency, which belongs to the activity of decentralization that has not been recognized, although digital currency also has some attributes of electronic currency.

The real economy is the field that our country must pay attention to in the future development and the foundation of our country
