Perhaps you should try some spelling variations:
chiet tach » chieu sach
luong manh » luong thanh, duong minh, luong van
duong manh » duong van
tung chua » cung chua, dung nhua, hung chu
cong chua » cong cua, cong chuc, con chua
ho chiet » ho chieu, ho thiet, hoc thiet
toan ban » van 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 chiet tach - manh ((tung chua) OR (cong chua)) nang ((luong manh) OR (duong manh)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - manh ((tung chua) or (cong chua)) nang ((luong manh) OR (duong manh)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - manh ((tung chua) or (cong chua)) nang ((luong manh) OR (duong manh)) toan ban*.
