for is used here to replace the meaning of spite. the translation for simplified chinese i believe is "尽管"

Essentially, there are two basic definitions of "for" that I can think of. One-the way "for" is used in your example-is a reference to something, whether it is time, a thing, or a person. Example: I got a pair of shoes for my friend. The other use of "for" would imply cause and effect between two things. Example: I went to the store, for I was out of milk. I hope this helps. :)
