Perhaps you should try some spelling variations:
ban duong » ban nong, lam duong
duong van » cong van, duong anh
shang hai » shang kai, dang hai, hong hai
wang ban » wang yan, wang dan, wang yang
ran ying » fan ying, jin ying, gao ying
chang ha » chang mae
tan ying » fan ying, tan yang, tan yong
dan yang » daun yang, tan yang, wang yang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ban duong van ((((dan yang) or (tan ying))) or (ran ying)) yi ((shang hai) OR (chang ha)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ban duong van ((((dan yang) OR (tan ying))) OR (ran ying)) yi ((shang hai) OR (chang ha)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ban duong van ((((dan yang) or (tan ying))) or (ran ying)) yi ((shang hai) OR (chang ha)) ;*".
