Perhaps you should try some spelling variations:
nhanh thanh » phan thanh
thieu sach » chieu sach, thien hach, hieu cach
nhanh tinh » hanh trinh, nhan sinh
chat nhung » chat ngung, thuat nhung, cua nhung
hoc thieu » toc thieu, hoc hien
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
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: hoc thieu sach - ((nhanh tinh) OR (nhanh thanh)) chat nhung ((cong dan) OR (cong san)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - ((nhanh tinh) or (nhanh thanh)) chat nhung ((cong dan) OR (cong san)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu sach - ((nhanh tinh) or (nhanh thanh)) chat nhung ((cong dan) OR (cong san)) toan tap*.
