Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
nhanh bac » nhanh ha, nhanh va
cong ban » cong bang, cong san, cong tan
phan lap » phan dau
tung va » trung va, tuong va, dung va

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)) - thanh tung va nhung cong ban ((phan lap) OR (nhanh bac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - thanh tung va nhung cong ban ((phan lap) or (nhanh bac))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - thanh tung va nhung cong ban ((phan lap) or (nhanh bac))*.
