I found I can use this extension to block "為你推薦"(Suggested for you) post.
create a new filter > if "any post content" > "matches css selector" > span:has-visible-text(為你推薦)

This Extension does the job done , many thanks and best regards for the Author

MattKruse, you are a godsend!

If there's a better addon to tame FB, I haven't found it.

Simply Amazing. Succefully used this to get rid of the timeline in order to kick my fb addiction.

It's an endless battle for Matt to work to make Facebook more usable for us, and he's doing a fantastic job.
