Perhaps you should try some spelling variations:
thanh trung » thanh tung
mot chieu » doi chieu, ho chieu
hoc thieu » toc thieu, hoc hien
hai nhung » thai nhung, hai hung, hay nhung
ai nhung » vai nhung, a nhung, thai nhung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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