Pay attention to the format of the letter, which is a respect for the recipient:
1, "Dear XX:" or "Dear XX:" (capitalized, don't forget the colon).
2. (Empty Box 2) Say hello to the other party first, and the words of the elders: "Hello!" ; The words of peers are "Hello!" Familiar words: "Long time no see!" Something like that
3, the text, each paragraph first empty two spaces, punctuation remember to occupy a space, if punctuation just catch up with the end of a line, don't write punctuation on a single line, just put it at the end of this line.
4. Ending format: a general greeting "from here" and "salute". The format is "from here" on another line and "salute" on the top line. Letters to the elderly often say "I wish you a long and healthy life", letters to friends often say "I wish you success in your work" and letters to younger generations often say "I wish you progress in your studies".
5. Author's signature (right) and writing date (right).
If you write a physical letter, you should also write an envelope carefully.
