Perhaps you should try some spelling variations:
nhanh tinh » nhanh thanh, hanh trinh, nhan sinh
quang tuan » quang thanh, quan luan, quang cua
tieu xanh » tieu danh, chieu xanh, dieu hanh
quang ban » quang binh, quang tran, qua ban
danh toan » anh toan, dan toan, dang toan
manh toan » thanh toan, anh tuan, tinh toan

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 tieu xanh - nhanh tinh ((quang ban) OR (quang tuan)) cong ((danh toan) OR (manh toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - nhanh tinh ((quang ban) OR (quang tuan)) cong ((danh toan) or (manh toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - nhanh tinh ((quang ban) OR (quang tuan)) cong ((danh toan) or (manh toan)) tap*.
