Perhaps you should try some spelling variations:
thanh tung » thanh cong
tong cong » trong cong, cong cong, dung cong
tung cua » trung cua, tuong cua, dung cua
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
khan cap » than cap, khoan cam, phan cac
khan ap » han ap, khan dam
o cuu » ho cuu, so cuu, _ cuu

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: ((o cuu) OR (_ nuu)) tinh - thanh tung cua tong cong dan ((khan cap) OR (khan ap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((o cuu) or (_ nuu)) tinh - thanh tung cua tong cong dan ((khan cap) OR (khan ap))~".
• Adding a wildcard symbol may retrieve word variants: ((o cuu) or (_ nuu)) tinh - thanh tung cua tong cong dan ((khan cap) OR (khan ap))*.
