can i apply for visa L and what special requirement i need?

Lama, you can apply for the L type in Jordan. Besides your passport, application form, recent passport-style photo, and passport copy, you are required to submit the original and photocopy of your entry permit or Jordan and an invitation letter from your husband. Perhaps the copy of your husband's Chinese temporary residence permit is also required.

my husband send to me three document 1. his copy of Chinese temporary residence permit 2. copy of his admissions note 3. certificate about his status
so can these three document with marriage contract alternative invitation letter? because his university don't give invitation letter, they give certificate about his status as invitation letter.
sorry for bothering
thank you

As I said, he could write the invitation letter on his own.
