Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
tang quan » tang luan, nang quan, thong quan
tong quan » thong quan, tong luan, luong quan
hang cong » dang cong, hang nong, bang cong
chu xanh » chu manh, chieu xanh, chuc danh
cong san » cong tac
san tuan » van tuan, san luan, san quan
tuan cau » toan cau, quan cau, tuan cu

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 xanh) OR (chua xang)) - hanh ((tang quan) OR (tong quan)) hang cong san tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chua xang)) - hanh ((tang quan) OR (tong quan)) hang cong san tuan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chua xang)) - hanh ((tang quan) OR (tong quan)) hang cong san tuan cau*.
