Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
mot trieu » mot chieu, mot tri, mon triet
tang van » dang van, hoang van, trong van
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
tang va » trang va, thang va, tang vat

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "mot trieu tinh - hanh ((tang va) OR (tang van)) nhung cong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: mot trieu tinh - hanh ((tang va) OR (tang van)) nhung cong dan ((toan cau) OR (toan ban))*.
