Perhaps you should try some spelling variations:
dung cong » dung trong
chu nang » chuc nang, chua nang, cuu nang
long cua » luong cua, dong cua, song cua
cong cua » cong cu, dong cua, huong cua
cong dan » cong san, cong tan, huong dan
tho chu » theo chu, cho chu, ho chu
ca cau » cua cau, cac cau, can cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: tho chu nang - nhanh ((long cua) or (cong cua)) dung cong dan ca cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tho chu nang - nhanh ((long cua) OR (cong cua)) dung cong dan ca cau*.
