Perhaps you should try some spelling variations:
lang yanling » wang yanling, wang yangming, zhang yunling
hoang making » ang making, change making, road making
making using » making use
kim hoang » kim young, kim song, kay hoang
using du » using due, using dt, using dual
yang yi » yang xi, yang jui

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: lang yanling ((((yang yi) OR (yang di))) OR (yang judy)) kim hoang making using du ;~.
• Adding a wildcard symbol may retrieve word variants: lang yanling ((((yang yi) or (yang di))) or (yang judy)) kim hoang making using du ;*.
