Perhaps you should try some spelling variations:
long thanh » luong thanh, long han, long trinh
child fall » child farm, child hill, child family
thanh two » than two
two child » who child, ilo child
yang july » yang judy, yang jui, yang jun
yang xi » yang yi, yang jui
wang » wing, wan, lang

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: long thanh two child fall ((((yang di) OR (yang xi))) OR (yang july)) wang hua ;~.
• Adding a wildcard symbol may retrieve word variants: long thanh two child fall ((((yang di) or (yang xi))) or (yang july)) wang hua ;*.
