Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sang » chieu sach, chieu xanh, hieu lang
hanh dung » thanh dung, anh dung, hanh dong
quan dong » quang dong, quan hoang, quan trong
quan long » quan lang, quan hoang, quan trong
tac thanh » bac thanh, cac thanh, tcc thanh
thanh lap » thanh san, phan lap, thanh hai
cong tac » cong ty

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 chieu sang - hanh dung ((quan dong) OR (quan long)) cong tac thanh lap~.
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - hanh dung ((quan dong) or (quan long)) cong tac thanh lap*.
