Perhaps you should try some spelling variations:
trung tuan » trung thanh, trung tam, tran tuan
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
cong cong » cong dong, trong cong, dung cong
tang cua » mang cua, hang cua, tang luan
cong dan » cong san, cong tan, huong dan
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 ((tang cua) OR (trung tuan)) cong cong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((tang cua) or (trung tuan)) cong cong dan van ban*.
