Perhaps you should try some spelling variations:
chuan rain » than rain
yang mind » yang cindy, yang jin, tang min
sang minh » kang minah, anh minh, song min
shang hai » shang kai, dang hai, hong hai
chang ha » chang mae
wan yan » wang yan, nan yan, wai yan
yan say » can say

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