Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu manh » hieu nganh, dieu hanh, hien hanh
cap nhung » cam nhung, dap nhung, canh nhung
vap nhung » va nhung, ve nhung, voi nhung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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 ((hieu manh) OR (chieu xanh)) - thanh trung ((cap nhung) OR (vap nhung)) cong dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (chieu xanh)) - thanh trung ((cap nhung) OR (vap nhung)) cong dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (chieu xanh)) - thanh trung ((cap nhung) OR (vap nhung)) cong dan toan tap*.
