Perhaps you should try some spelling variations:
phan cong » thanh cong
chu sang » thu sang, chieu sang, chuc nang
chu bang » thu bang, chuc nang, chu quang
anh mang » hanh mang, anh bang, anh dang
mang cua » manh cua, dung cua, ban cua
cua phan » cua nhan, cua phap, cua han
dan toan » van toan, manh toan, xuan toan
dan than » dan chan, ban than, van than

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: cho ((chu sang) OR (chu bang)) - anh mang cua phan cong ((dan toan) OR (dan than)) cao~.
• Adding a wildcard symbol may retrieve word variants: cho ((chu sang) or (chu bang)) - anh mang cua phan cong ((dan toan) or (dan than)) cao*.
