What should I say if someone gives me a calligraphy painting?

Asking for calligraphy, to put it mildly, is called Mo Bao. First of all, you need your attitude towards each other. You should know something about each other's calligraphy. And greatly appreciated it. If you don't understand. The other party will be a little unhappy. If you ask someone to write a pair, you should generally tell the calligrapher the content of the words to be written according to your own preferences, and also tell the calligrapher the size of the ruler to be written and whether the banner is vertical according to the position where you hang it. There is also a problem of financing (that is, money), which can be handled flexibly according to the relationship, and people who ask for help should be polite.
