What this hospital used to do was "Face to Face Life" by Beijing TV Station, which is said to be on-site injection. I think it's good to dare to inject on the spot. At most, it's a show, so as not to dare to do it on the spot. So my personal opinion is that it should be good.
There are many micro-doctors who are not very good at technology, but dare to spend money on advertising, so typing, kissing and micro-plastic surgery are also risky. You must choose for yourself.
