possible Yongzheng plate

I am wondering if this is a Yongzheng plate, because the marks are kind of similar to some that I have seen. Is that the symbol for 'happiness' or another? I look forward to your reply..

Oh.. and that other mid Qing plate I enquired about does have the oblique bottom rim. It is very oblique on the inner side and the outer is a little bit as well.

Thanks for all of your help!!
