Perhaps you should try some spelling variations:
thanh trinh » hanh trinh, thanh tinh, thanh binh
theo chieu » theo tieu, theo chu, thi chieu
bang duong » bang suong, bang tuong, tang duong
duong manh » duong van
luat bang » luat ban, luat bong, luat quang
ho chieu » hoc thieu, doi chieu, mot chieu
toan cao » toan ban
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: ((ho chieu) OR (theo chieu)) xanh - thanh trinh luat bang duong manh ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - thanh trinh luat bang duong manh ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - thanh trinh luat bang duong manh ((toan cao) or (toan tap))*.
