Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
tranh cua » doanh cua, manh cua
trung cua » truong cua, trung tuan, trung cap
cong tac » cong ty
quan lam » quang lam, quan lap, quan am

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 - hanh ((tranh cua) OR (trung cua)) nhung cong tac quan lam~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((tranh cua) or (trung cua)) nhung cong tac quan lam*.
