Perhaps you should try some spelling variations:
yang july » yang judy, yang jun
chi shang » chin chang, wei shang, chih hang
yang jui » yang judy, yang di, yang xi
giao chi » hao chi, jiao che, thao chi
cong sun » cong shu, wing sun
cong van » congo can, duong van
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 jui) OR (yang july)) giao chi shang jin ((cong sun) OR (cong van)) ;~.
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((yang jui) or (yang july)) giao chi shang jin ((cong sun) or (cong van)) ;*.
