Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
thi chieu » thi chien, thi hieu, theo chieu
hanh dung » anh dung, hanh dong, manh dung
dung cong » dung trong
theo chu » theo chieu, cho chu, chao chu
qua dung » quang dung, su dung, qua song
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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: ((thi chieu) OR (theo chu)) xanh - ((hanh dung) OR (thanh dung)) qua dung cong dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (theo chu)) xanh - ((hanh dung) OR (thanh dung)) qua dung cong dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((thi chieu) or (theo chu)) xanh - ((hanh dung) OR (thanh dung)) qua dung cong dan toan tap*.
