Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
manh trung » manh tung, thanh trung, manh hung
luong cong » trong cong, cong cong, tong cong
trung dai » truong dai, truong dao, trung tam
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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: ho chieu xanh - manh trung dai ((luong cong) OR (dung cong)) dan than cap~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - manh trung dai ((luong cong) or (dung cong)) dan than cap*.
