Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
chua tinh » cua tinh, cha tinh, thuat tinh
hanh mang » nhanh mang, hanh trang, nhanh lang
cong cong » cong dong, trong cong, dung cong
chu tinh » chau tinh, cuu tinh, chu tich
mang cua » manh cua, dung cua, ban cua
tap quan » tac quan, hai quan

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: theo ((chu tinh) OR (chua tinh)) - hanh mang cua cong cong ((thanh toan) OR (tap quan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu tinh) OR (chua tinh)) - hanh mang cua cong cong ((thanh toan) or (tap quan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu tinh) OR (chua tinh)) - hanh mang cua cong cong ((thanh toan) or (tap quan)) cau*.
