Perhaps you should try some spelling variations:
cang thang » cong thanh, dang thanh
thang long » thanh cong
hang hang » nang hang, hung thang, lang thang
doan chan » doan chuan, doan phan, doanh nhan
chu xanh » chu manh, chieu xanh, chua xang
va thang » van thang, va thanh, va thong
dan chan » dan gian, dan ca, van chat
cho chu » cho thue

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: cho chu xanh - ((hang hang) OR (cang thang)) va thang long ((doan chan) OR (dan chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chu xanh - ((hang hang) or (cang thang)) va thang long ((doan chan) OR (dan chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: cho chu xanh - ((hang hang) or (cang thang)) va thang long ((doan chan) OR (dan chan)) cau*.
