Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh sinh » thanh binh, thanh tinh, thanh vinh
phan cong » thanh cong
sinh cua » manh cua, dinh cuu, sinh va
cua phan » cua nhan, cua phap, cua han
san tai » sang tai, van tai, ban tai
han tai » hang tai, nhan tai, van tai

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