Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thong cong » trong cong, tong cong, phong chong
tranh vat » trinh vat, tranh va, tranh van
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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)) - canh tranh vat ((thong cong) OR (thong thong)) dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - canh tranh vat ((thong cong) OR (thong thong)) dan than cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - canh tranh vat ((thong cong) OR (thong thong)) dan than cap*.
