Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
tranh van » tran van, trinh van, thanh van
dang cong » dung cong
chu xanh » chu manh, chieu xanh, chuc danh
van dang » van dong, van dung, van nang
dan than » dan chan, ban than, van than
van tan » van tuan, van ban, van tai

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)) - canh tranh van dang cong ((van tan) OR (dan than)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chua xang)) - canh tranh van dang cong ((van tan) or (dan than)) ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chua xang)) - canh tranh van dang cong ((van tan) or (dan than)) ban*.
