Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
canh trinh » canh tranh, hanh trinh, canh tinh
tong cong » trong cong, dung cong, dang cong
cong cong » cong dong, trong cong, dung cong
trinh va » trinh van, trinh vat, trinh ve
dan phan » doan phan, dan chan, van phan
phan cac » nhan cach, phan dau, phan lap

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: doi ((chieu xanh) OR (chieu sang)) - canh trinh va ((tong cong) OR (cong cong)) dan phan cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sang)) - canh trinh va ((tong cong) or (cong cong)) dan phan cac~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) OR (chieu sang)) - canh trinh va ((tong cong) or (cong cong)) dan phan cac*.
