Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung pham » trung phan, tung pham, trung phat
hop nhieu » hoc thieu, ho chieu, he nhieu
pham hang » pham hoang, pham hong, pham hanh
hang cong » dang cong, hang nong, bang cong
ho nhieu » ho chieu, he nhieu, hoc thieu
cong dan » cong san, cong tan, huong dan
toan ban » van ban
toan cao » toan tap

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 nhieu) OR (hop nhieu)) tang - thanh trung pham hang cong dan ((toan ban) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho nhieu) OR (hop nhieu)) tang - thanh trung pham hang cong dan ((toan ban) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((ho nhieu) OR (hop nhieu)) tang - thanh trung pham hang cong dan ((toan ban) or (toan cao))*.
