Basically, no, no.

This is only the expression of the will of both parties in the preliminary negotiation stage, which is divided into oral and written situations.

Oral is more flexible, leaving room.

Let people have evidence to check in writing, and their space will be less.

However, in view of "I have my own national conditions here in the Qing Dynasty", for me, shopping around is just a general statement, and more importantly, it is to please others by eating, drinking, whoring and gambling. Of course, there is a basic premise, unless the other party really doesn't understand, then you can sell things even if they are rotten. If the other party still has smart people and preparation, even if you try hard to engage in eating, drinking, whoring and gambling, it is no use. They may say that they have been appointed and decided. But you ask me ... you must ask me. I think it's just Dong Xiansen's porcelain, not porcelain. When I say porcelain is porcelain, I'll make this clear. ) If it's you by default, get busy. That's all that matters. If it is not you by default, send a real white paper to the inviter, and it will become a textbook for primary school students. There is nothing wrong with any strategy.

So, first find out if the other person has an understanding person. If there is someone who knows, then find out if there is an appointment and if there is a default. If not, then do it quickly and strive for default and appointment. Understand?
