Perhaps you should try some spelling variations:
thanh tung » thanh cong
thanh toan » thanh hoa, thanh san, tinh toan
tung tuan » trung tuan, hung tuan, quang tuan
bang cong » dang cong, hang cong, dung cong
bang song » nang song
chi xanh » chi anh, chi danh, chieu xanh
chi hanh » chi nhanh, chi thanh, thi hanh
toan tap » toan ban

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: doi ((chi xanh) OR (chi hanh)) - thanh tung tuan ((bang cong) OR (bang song)) thanh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) or (chi hanh)) - thanh tung tuan ((bang cong) OR (bang song)) thanh toan tap~".
• Adding a wildcard symbol may retrieve word variants: doi ((chi xanh) or (chi hanh)) - thanh tung tuan ((bang cong) OR (bang song)) thanh toan tap*.
