Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chau tinh » cuu tinh, ha tinh, cua tinh
lang luan » hang luan, bang luan, lang xuan
tang luan » dung luan
cua sinh » hoa sinh, va sinh
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than ban » thanh ban, toan ban, than man

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 (cua sinh)) - nhanh ((lang luan) OR (tang luan)) nhung cong dan than ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) or (cua sinh)) - nhanh ((lang luan) OR (tang luan)) nhung cong dan than ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chau tinh) or (cua sinh)) - nhanh ((lang luan) OR (tang luan)) nhung cong dan than ban*.
