Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wang yong » wang yang, wang hyoung, wang yan
sang minh » kang minah, anh minh, song min
dong bin » dong sin, dong di, dann bin
hua rent » hua ren
yan minh » tuan minh, yang mind, yuan ming
cong hai » hong hai, dang hai, cong van

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang yang) or (wang yong))) or (dong bin)) ya hua rent ((yan minh) OR (sang minh)) cong hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yang) OR (wang yong))) OR (dong bin)) ya hua rent ((yan minh) OR (sang minh)) cong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) or (wang yong))) or (dong bin)) ya hua rent ((yan minh) OR (sang minh)) cong hai ;".
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (wang yong))) or (dong bin)) ya hua rent ((yan minh) OR (sang minh)) cong hai ;*.
