Every time I travel, I always meet someone who says I remember to bring a personal letter. What should I answer at this time?

Calligraphy usually refers to small gifts or special gifts brought to relatives and friends when traveling or coming back from home. Generally speaking, calligraphy refers to Hong Kong, Guangdong and Macao. When someone says this, the speaker may find it difficult to go to a place. Remind you to bring some handwritten letters and answer: OK, thank you. Or someone close to me reminds me that I want you to bring him some handwritten information, and answers: I'll bring you some if you want. Under normal circumstances, there is nothing to say when meeting, just say it casually, don't care.
