Perhaps you should try some spelling variations:
trung thanh » truong thanh
theo chieu » theo tieu, theo chu, thi chieu
trung tuan » trung tam, tran tuan, truong thanh
nhung cong » dung cong, thong cong, hang cong
ho chieu » hoc thieu, doi chieu, mot chieu
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: ((ho chieu) OR (theo chieu)) xanh - thanh ((trung tuan) OR (trung thanh)) nhung cong dan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - thanh ((trung tuan) OR (trung thanh)) nhung cong dan van ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - thanh ((trung tuan) OR (trung thanh)) nhung cong dan van ban*.
