Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
ying ying » ying yang, yirong ying, liang ying
ying jin » yang jin, jing ji, yang jie
yang li » yang lin, yang di, yang xi
ying a » buying a, laying a, ying hua
a gene » a genre, a gender, a gentle
hai » hadi, haji, hari

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR wan) ying ying a gene ((yang li) OR (((yang liang) OR (ying jin)))) dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or wan) ying ying a gene ((yang li) or (((yang liang) or (ying jin)))) dang hai ;*.
