Perhaps you should try some spelling variations:
long thanh » luong thanh, long han, long trinh
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
shang hai » shang kai, dang hai, chang ha
chai dan » chai onn, chai tam, shi dan
dan yang » daun yang, tan yang, adam yang
yang jin » yang jie, yang jun, ying jin
ka chai » ka chuan, kim chai

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: ((yang yang) OR (wang yang)) ka chai dan yang jin ((shang hai) OR (long thanh)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) OR (wang yang)) ka chai dan yang jin ((shang hai) or (long thanh)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) OR (wang yang)) ka chai dan yang jin ((shang hai) or (long thanh)) ;*.
