Perhaps you should try some spelling variations:
khong cong » thong cong, khong cang, chong cong
cua khong » hua khong, cua phuong, cua thuong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
anh tang » anh bang, anh dang, anh sang
anh nang » ganh nang, anh bang, anh dang
dan than » dan chan, ban than, van than

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: theo chu xanh - ((anh tang) OR (anh nang)) cua khong cong ((dan than) OR (dan gian)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((anh tang) OR (anh nang)) cua khong cong ((dan than) or (dan gian)) cao~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((anh tang) OR (anh nang)) cua khong cong ((dan than) or (dan gian)) cao*.
