Perhaps you should try some spelling variations:
thanh trung » thanh tung
tuong manh » duong manh, luong manh, tung manh
hoc chieu » hoc thieu, ho chieu, hoc dieu
manh toan » thanh toan, anh tuan, tinh toan
cua phap » va phap, cua nha, cua nhan
toan ban » van ban
cua han » cua hang, cua nhan, cua phan

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 chieu) OR (hoc hien)) xanh - thanh trung ((cua han) OR (cua phap)) tuong manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (hoc hien)) xanh - thanh trung ((cua han) or (cua phap)) tuong manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (hoc hien)) xanh - thanh trung ((cua han) or (cua phap)) tuong manh toan ban*.
