Perhaps you should try some spelling variations:
trung tuan » trung thanh, trung tam, tran tuan
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
trung cua » truong cua, trung cap, dung cua
doc hieu » toc thieu, hoc hien
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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: ((doc hieu) OR (hoc thieu)) xanh - thanh ((trung cua) OR (trung tuan)) nhung cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (hoc thieu)) xanh - thanh ((trung cua) OR (trung tuan)) nhung cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (hoc thieu)) xanh - thanh ((trung cua) OR (trung tuan)) nhung cong dan than cap*.
