Perhaps you should try some spelling variations:
chuan rain » than rain
hai chuan » say chuan, ka chuan, tai chun
yang mind » yang cindy, yang jin, tang min
sang minh » kang minah, anh minh, song min
wan dang » wang yang, wan daud, dan dana
hong hai » shang hai, zhong tai, hong tan
chang ha » chang mae

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: wan dang hai chuan rain ((yang mind) OR (sang minh)) ((hong hai) OR (chang ha)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan dang hai chuan rain ((yang mind) OR (sang minh)) ((hong hai) or (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan dang hai chuan rain ((yang mind) OR (sang minh)) ((hong hai) or (chang ha)) ;*.
