Perhaps you should try some spelling variations:

chieu sang » chieu sach, chieu xanh, hieu lang
thanh sinh » thanh binh, thanh tinh, thanh vinh
cua phan » cua phap, cua han, qua phan
cua nhan » ca nhan, cua ngan, cua nha
cong san » cong tac
san tai » sang tai, van tai, han tai
tai cao » thai cao, tao cao, tai sao

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - thanh sinh ((cua phan) OR (cua nhan)) cong san tai cao~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - thanh sinh ((cua phan) OR (cua nhan)) cong san tai cao*.
