Perhaps you should try some spelling variations:
wang yang » wang liang, wang yanling
sang minh » kang minah, anh minh, song min
hua rent » hua ren
tang min » chang min, yang mind, tang li
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai
yi hua » li hua, ya hua, yi hui

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: ((wang yang) OR (wang yan)) yi hua rent ((((tang min) OR (sang minh))) OR (yang jin)) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang yan)) yi hua rent ((((tang min) OR (sang minh))) or (yang jin)) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang yan)) yi hua rent ((((tang min) OR (sang minh))) or (yang jin)) hong hai ;*.
