Perhaps you should try some spelling variations:
thanh thuong » thanh huong, thanh chuong, thanh phuong
thuc dung » thuoc dung, thuy dung, tuc dung
dung cong » dung trong
hoc dieu » hoc thieu
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
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 dieu) OR (hoc hien)) xanh - thanh thuong thuc dung cong dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc dieu) or (hoc hien)) xanh - thanh thuong thuc dung cong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc dieu) or (hoc hien)) xanh - thanh thuong thuc dung cong dan ((toan cau) OR (toan ban))*.
