Perhaps you should try some spelling variations:
thanh trang » thanh trung, hanh trang, thanh thang
thieu xanh » chieu xanh, thien anh, thien danh
nhung cong » dung cong, thong cong, hang cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trang va » tran van, hang va
dan than » dan chan, ban than, dan toan
van than » van thanh, van thang, van tuan

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: hoc ((thieu xanh) OR (hieu manh)) - thanh trang va nhung cong ((dan than) OR (van than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (hieu manh)) - thanh trang va nhung cong ((dan than) or (van than)) cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (hieu manh)) - thanh trang va nhung cong ((dan than) or (van than)) cao*.
