Perhaps you should try some spelling variations:
thanh tung » thanh cong
che chinh » te chinh
dung cong » dung trong
tung cap » trung cap, cung cap, thong cap
cap dung » ap dung, cao dung, chan dung
cong tan » cong tac, cong san, cong thanh
toan tap » toan ban
phan dau » phan tu, hang dau

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: che chinh sach - thanh tung cap dung cong tan ((toan tap) OR (((phan lap) OR (phan dau))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "che chinh sach - thanh tung cap dung cong tan ((toan tap) or (((phan lap) OR (phan dau))))~".
• Adding a wildcard symbol may retrieve word variants: che chinh sach - thanh tung cap dung cong tan ((toan tap) or (((phan lap) OR (phan dau))))*.
