How to write the format and writing of Qing family letter?

The format and writing of letters in the Qing Dynasty all started with the title of the top case, and some of them can also add certain qualified modifiers. For example, in the letter from dear family to elders, if it is a close relative, just write the title, not the name. For parents, brothers and sisters and other relatives, they will write the title of relationship, such as menstruation's menstruation. The letter format of the letter from home mainly includes five parts: the address at the end of the text, the signature and the date and address, which are written above the letter header. To clarify the relationship between yourself and the recipient, the text usually begins with a greeting and is written on the next line of the address, and then the main part of the text is what the writer wants to say.
