Perhaps you should try some spelling variations:
thuc tien » thuc hien
hanh tang » hanh trang, anh tang, hanh mang
qua trong » quan trong, qua trinh, qua song
tang qua » tang quan, tang cua, tang quy
cong dan » cong san, cong tan, cong dong
toan cau » toan cao, toan ban, toan tai
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: thuc tien thinh - hanh tang qua trong ((cong dan) OR (huong dan)) ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: thuc tien thinh - hanh tang qua trong ((cong dan) or (huong dan)) ((toan cau) or (toan tap))*.
