The reason why you choose to say a treasure, a certain east instead of directly saying the full name is another problem, that is, the problem of network promotion. These businesses will buy all kinds of black public relations, they find negative comments through keyword screening, and delete a lot of posts, so they can only say their full names! That is, although you know I'm talking about you, you can't say I'm talking about you just because I didn't name you! This is also a kind of self-protection for consumers!
