Perhaps you should try some spelling variations:
thanh tung » thanh cong
chau tinh » cuu tinh, ha tinh, cua tinh
tuan ban » tuan bang, toan ban, luan ban
ban cong » bang cong, van cong, phan cong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tap
ho chau » ha chau, ho chu, o chau

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 chau tinh - ((thanh trung) OR (thanh tung)) tuan ban cong tan ((toan cau) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - ((thanh trung) OR (thanh tung)) tuan ban cong tan ((toan cau) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - ((thanh trung) OR (thanh tung)) tuan ban cong tan ((toan cau) or (van ban))*.
