(Looking through the Internet, "we don't recruit middle-aged people over the age of 35" and "you can scold middle-aged people if you want to, they dare not change jobs"...these are all correct, and so are the facts. But this kind of writing can't solve the problem at all except to create anxiety. Because #工场热都# is an inevitable experience for everyone in their career development. It is really not too common to go up and down, but not reconciled to going down. Taking programmers as an example, after several years of project experience accumulation, you will encounter two choices. One is to be very passionate about technology, and this kind of person will gradually become a master of technology.)
