Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban 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: ((hoc thieu) OR (hoc hien)) xanh - thanh ((trung cua) OR (trung cap)) nhung cong tan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) xanh - thanh ((trung cua) or (trung cap)) nhung cong tan than cap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) xanh - thanh ((trung cua) or (trung cap)) nhung cong tan than cap*.
