Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
zhang qian » zhang qin, zhang tian, zhang qilun
zhang jian » zhang fan, shang jin
yang ping » yang jing, yang using, zhang ping
jia cheng » jia shen, jia zhang, xi cheng
jeong su » jeong _, jeong mi, jeong 情
wang » wing, wan

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: (wang OR lang) ((yang ping) OR (yang liang)) jia cheng ((zhang qian) OR (zhang jian)) jeong su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((yang ping) or (yang liang)) jia cheng ((zhang qian) OR (zhang jian)) jeong su ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((yang ping) or (yang liang)) jia cheng ((zhang qian) OR (zhang jian)) jeong su ;*.
