Perhaps you should try some spelling variations:
trong dang » truong dang, trong dan, trong dung
trong dong » trong cong, trong nong, trong dung
canh manh » lanh manh, canh tranh, cach mang
ho chieu » theo chieu, hoc thieu, doi chieu
manh qua » manh quan, manh cua, danh qua
qua dung » quang dung, su dung, qua song
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: ((ho chieu) OR (hoc hien)) xanh - canh manh qua dung ((trong dang) OR (trong dong)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc hien)) xanh - canh manh qua dung ((trong dang) OR (trong dong)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc hien)) xanh - canh manh qua dung ((trong dang) OR (trong dong)) toan ban*.
