Perhaps you should try some spelling variations:
chieu sang » chieu sach, hieu lang, nhieu tang
chieu xanh » chieu sach, chieu tinh, hieu manh
thong cong » trong cong, tong cong, thong thong
hanh hanh » hanh han, xanh hanh, nhanh thanh
cong tinh » cong trinh, cong vinh, long tinh
va thong » va thuong, va phuong, he thong
toan tap » toan ban
hanh va » hang va, hanh vi

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 sang) OR (chieu xanh)) - hanh hanh va thong cong tinh toan tap~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chieu xanh)) - hanh hanh va thong cong tinh toan tap*.
