Perhaps you should try some spelling variations:
thuat nhung » thuat hung, thuat chung, thuat chuong
chieu xanh » chieu sach, chieu sang, chieu tinh
tran thuat » trong thuat, trien thuat, tran tuan
nhung cong » dung cong, thong cong, hang cong
manh tran » manh toan, manh tuan, canh tranh
tan toan » tan tran, van toan, dan toan
tap toan » tap doan, tap quan, bai toan
va tinh » may tinh

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