Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, hanh trinh
trung ban » trung van, trung tuan, trung phan
trong ban » trong san, trong tan, trong quan
trung can » trung cap, trung van, trong can
ho trieu » mot trieu, 25 trieu, 30 trieu
trang va » tran van, hang va
than man » than ma, thanh san, tran manh
va dung » van dung, va duong, vat dung

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 trieu tinh - hanh trang va dung ((((trung ban) OR (trong ban))) OR (trung can)) than man~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - hanh trang va dung ((((trung ban) OR (trong ban))) or (trung can)) than man~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - hanh trang va dung ((((trung ban) OR (trong ban))) or (trung can)) than man*.
