Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang
nhieu tang » hieu lang, nhiet nang
nhung dung » phuong dung, ung dung, thong dung
dung manh » duong manh, dung danh, hung manh
manh toan » thanh toan, anh tuan, tinh toan
tranh va » tranh van, trang va, trinh va
toan cau » toan cao, toan ban, toan tap

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: ho ((((chieu xanh) OR (chieu sang))) OR (nhieu tang)) - canh tranh va nhung dung manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu sang))) or (nhieu tang)) - canh tranh va nhung dung manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (chieu sang))) or (nhieu tang)) - canh tranh va nhung dung manh toan cau*.
