1: All documents must be published in English.
2. If there are two languages in a document, (1) should meet the requirements. (2) If there are any problems in the future, the English expression shall prevail.
3. The signature of the shipping company and other things should be in Chinese font, which should be no problem. But there must be a signature where necessary, which is most recognized by foreigners.
I suggest you scan the unsigned documents before they come out, and then send them to the other party for confirmation (not only the format, but also the content) to avoid unnecessary trouble.
Good luck with your work.
If it helps you, don't forget to adopt it ~
