Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
hoc thieu » toc thieu, hoc hien
doi chieu » doc hieu, doi chi, ho chieu
tran nang » tra nang, tran dang, tran quang
nang tong » nang trong, nang song, nang dong
tong cong » trong cong, cong cong, dung cong
cong dan » cong san, cong tan, huong dan
toan ban » van 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: ((hoc thieu) OR (doi chieu)) xanh - thanh tran nang tong cong dan ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chieu)) xanh - thanh tran nang tong cong dan ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chieu)) xanh - thanh tran nang tong cong dan ((toan tap) OR (toan ban))*.
