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
trung cua » truong cua, trung tuan, trung cap
manh cua » doanh cua
cong dan » cong san, cong tan, huong dan
ban cua » ban quan
dan van » dang van, doan van, dao van

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 ((trung cua) OR (((manh cua) OR (ban cua)))) nhung cong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((trung cua) or (((manh cua) or (ban cua)))) nhung cong dan van ban*.
