In the lower right corner of the letter, use the best English signature. If it's an ordinary letter, it's usually a text separated by one line, then write the best wishes or best greetings, and then write an English letter with a blank line. Business letters usually use sincerity or yours. Don't write+yours seriously. There is something wrong with grammar. You should be serious.

The end of the English letter signature is one or two lines below the text, starting from the right middle of the stationery, with the first word capitalized and a comma at the end of the sentence. Different objects, the conclusion is written differently.

After writing a letter, I suddenly remembered something I missed. At this time, I will use P.S. to express it, and then I can write out the missing words. I want to make a long story short. Usually on the left below the signature at the end of the letter, it should be flush with the text. Note: in formal letters, avoid using postscript.
