Perhaps you should try some spelling variations:
thanh trung » thanh tung
thanh duong » thanh huong, thanh cuong, thanh chuong
thanh vuong » thanh huong, thanh cuong, thanh chuong
thanh dung » thanh tung, thanh hung, hanh dung
hien manh » hien hanh, tien manh, hieu manh
cong dan » cong san, cong tan, huong dan
dan phan » doan phan, dan chan, van phan

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: hoc hien manh - thanh trung ((thanh dung) OR (((thanh duong) OR (thanh vuong)))) cong dan phan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien manh - thanh trung ((thanh dung) or (((thanh duong) OR (thanh vuong)))) cong dan phan tu~".
• Adding a wildcard symbol may retrieve word variants: hoc hien manh - thanh trung ((thanh dung) or (((thanh duong) OR (thanh vuong)))) cong dan phan tu*.
