Perhaps you should try some spelling variations:
thuyet danh » thuyet anh, khuyet danh, thuyet canh
thuyet dan » thuyet va, thuyet bai, truyen dan
nhung cong » dung cong, thong cong, hang cong
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
tang cua » mang cua, hang cua, tang luan
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
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: hoc ((thuyet danh) OR (thuyet dan)) - hanh tang cua nhung cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thuyet danh) OR (thuyet dan)) - hanh tang cua nhung cong dan ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thuyet danh) OR (thuyet dan)) - hanh tang cua nhung cong dan ((toan cau) or (toan cao))*.
