Perhaps you should try some spelling variations:
qian yirong » qian rong, qian zhihong
daun yang » dan yang, du yang
jia zhang » jie zhang, jia zhangke, xiao zhang
tan yang » dan yang, tan ying, tan yong
gang hai » dang hai, shang hai, eang hay
ying ji » ying jin, jing ji, yang jie
un yang » dan yang, hui yang, yin yang
li gang » liu gang, ii gang, i gang

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: qian yirong ying ji ((((((daun yang) OR (un yang))) OR (tan yang))) OR (jia zhang)) li gang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yirong ying ji ((((((daun yang) OR (un yang))) or (tan yang))) or (jia zhang)) li gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: qian yirong ying ji ((((((daun yang) OR (un yang))) or (tan yang))) or (jia zhang)) li gang hai ;*.
