Perhaps you should try some spelling variations:
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
cuong tap » luong tap, cong tac, luong tai
theo chu » theo chieu, cho chu, chao chu
chu bang » thu bang, chuc nang, chu quang
cong tap » cong tac, cong tan, tong tap
doan ban » doanh ban, toan ban, doan van

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: theo chu bang - hanh ((trang cua) OR (trung cua)) tong ((cong tap) OR (cuong tap)) doan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu bang - hanh ((trang cua) or (trung cua)) tong ((cong tap) OR (cuong tap)) doan ban~".
• Adding a wildcard symbol may retrieve word variants: theo chu bang - hanh ((trang cua) or (trung cua)) tong ((cong tap) OR (cuong tap)) doan ban*.
