Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chau tinh » ha tinh, cua tinh, cac tinh
trinh vat » trinh luat, sinh vat, trinh han
trinh van » trinh han, trinh quan, trinh toan
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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: ho ((chau tinh) OR (cuu tinh)) - hanh ((trinh vat) OR (trinh van)) nhung cong dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) OR (cuu tinh)) - hanh ((trinh vat) or (trinh van)) nhung cong dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chau tinh) OR (cuu tinh)) - hanh ((trinh vat) or (trinh van)) nhung cong dan toan tap*.
