Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu tinh » trieu tinh, lieu tinh, chau tinh
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
manh va » hanh va, anh va, lanh va
minh va » tinh va, sinh va, sinh vat

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 tinh - canh ((manh va) OR (minh va)) nhung cong dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - canh ((manh va) or (minh va)) nhung cong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - canh ((manh va) or (minh va)) nhung cong dan ((toan cau) OR (toan ban))*.
