Perhaps you should try some spelling variations:
nhieu tang » chieu sang, nhiet nang
nhung cong » dung cong, thong cong, hang cong
hieu lang » chieu sang, hieu quang, hieu van
cua nhung » va nhung
lanh ban » lanh bang, lang ban, doanh ban
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan tap » toan ban
ban cua » ban quan
chuc » thuc, chu, chua

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 ((((nhieu tang) OR (hieu lang))) OR (chuc nang)) - lanh ban cua nhung cong van toan tap~.
• Adding a wildcard symbol may retrieve word variants: theo ((((nhieu tang) or (hieu lang))) or (chuc nang)) - lanh ban cua nhung cong van toan tap*.
