Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
wei yang's » yiwei wang's
yan liang » wang liang, you liang, yan wang
judy long » judy young, study long
jaan hui » yuan hui
wei yang » pei yang, wei wang, wei shang
long du » long d, long do, long run

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: ((yan liang) OR (yang liang)) jaan hui ((wei yang) OR (wei yang's)) judy long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang liang)) jaan hui ((wei yang) OR (wei yang's)) judy long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang liang)) jaan hui ((wei yang) OR (wei yang's)) judy long du ;*.
