Perhaps you should try some spelling variations:
trong tinh » truong tinh, trong kinh, trong sinh
hanh dung » thanh dung, anh dung, hanh dong
luan dang » luan nang, luan danh, luan dong
long tinh » cong tinh, luong tin, dong tin
theo chu » theo chieu, cho chu, chao chu
ho chieu » theo chieu, hoc thieu, doi chieu
toan cao » toan ban, toan tap

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: ((theo chu) OR (ho chieu)) xanh - hanh dung luan dang ((long tinh) OR (trong tinh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (ho chieu)) xanh - hanh dung luan dang ((long tinh) OR (trong tinh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (ho chieu)) xanh - hanh dung luan dang ((long tinh) OR (trong tinh)) toan cao*.
