Perhaps you should try some spelling variations:
yang july » yang judy, yang jun
shang hai » shang kai, dang hai, chang ha
yang jui » yang judy, yang xi
yi hang » yi chang, yin hang, yi gang
hang yi » zhang yi, tang yi, zhang yin
yi chen » jui chen
yang yi » yang xi
tan yi » tang yi, tan li, tan ying

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: tan yi hang yi chen ((((yang yi) OR (yang di))) OR (((yang jui) OR (yang july)))) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: tan yi hang yi chen ((((yang yi) or (yang di))) or (((yang jui) or (yang july)))) shang hai ;*.
