1. "Three Preventions" means Three Preventions and protections. In the electronic instry, "Three Preventions" generally refer to "mould proof, moisture proof and salt fog proof" for electronic procts. In a broad sense, surface treatment is used to rece or eliminate the adverse effects of complex environment on the performance of electronic devices. The process that the manufacturers of electronic procts brush three proofing paint on the circuit board after proction and debugging is called "three proofing". The definition of "three proofs" mobile phone is very simple, that is, it has the functions of slight stproof, shockproof and waterproof, so it has always been loved by young users who love outdoor sports. The basic human prevention is to use people's own sensors (eyes, hands, ears, etc.) to detect and respond to the targets that hinder or destroy safety; We should delay or prevent the occurrence of danger by means of sound warning, intimidation, setting up barriers, weapons and so on. When our own strength is insufficient, we should send out signals for help, in order to expect to make further response and stop the occurrence of danger or deal with the danger that has occurred.

2. Which one is worth buying doesn't exist, because each one has its own different experience and function
at present, it is common in the market, such as:
Network (Xiao speaker), Xiaomi (Xiaoai speaker), Alibaba (tmall ELF), cheetah (Xiaobao speaker), etc

we have cooperated with (dingdong speaker) of iFLYTEK and Jingdong, and we have cooperated with (small chain speaker) of small chain technology and network, which can realize the mining function of blockchain
if you say which one is worth buying, you may have to first look at your own needs, such as brand, appearance, color, function, shape, sound, price, etc., to see what you prefer and what the price range is. Anyway, it's all from the big guys in China, so it's almost the same.

Zhao Gensheng glances at the tower and frowns as he passes by. He thinks that this song is about the suffering of people's livelihood, and it's weird. It's really disturbing. He did not look at the tower, Wu lowered his head through the downstairs crowd, anxious step for a moment
as soon as you bow your head, it's like a dark day. Xilong town has been on the rise recently. Yesterday, Feixun reported that the Xishan ore tower suddenly collapsed, burying more than 40 people, but he still has no idea whether he is alive or dead.
