Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thanh van » thanh san, thanh toan, thanh phan
so trieu » mot trieu, so dieu, so lieu
hoc dieu » hoc thieu, hoc hien
thanh va » hanh va, thanh ha, thanh ve
cong dan » cong san, cong tan, huong dan
dan can » dan chan, dan canh, dan ca
can cau » van cau, ban cau, ca cau

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: ((so trieu) OR (hoc dieu)) tinh - canh ((thanh va) OR (thanh van)) nhung cong dan can cau~.
• Adding a wildcard symbol may retrieve word variants: ((so trieu) or (hoc dieu)) tinh - canh ((thanh va) or (thanh van)) nhung cong dan can cau*.
