Perhaps you should try some spelling variations:
nhanh thanh » phan thanh, nhanh tinh
chieu sach » chinh sach, chiet tach, chieu sang
chieu xanh » chieu sang, chieu tinh, hieu manh
nhung cong » dung cong, thong cong, hang cong
hanh hanh » hanh han, xanh hanh, thanh thanh
cong tinh » cong trinh, cong vinh, long tinh
toan tap » toan ban

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 sach) OR (chieu xanh)) - ((hanh hanh) OR (nhanh thanh)) va nhung cong tinh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu xanh)) - ((hanh hanh) OR (nhanh thanh)) va nhung cong tinh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chieu xanh)) - ((hanh hanh) OR (nhanh thanh)) va nhung cong tinh toan tap*.
