Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
theo chieu » theo tieu, ho chieu, theo chu
chieu tinh » trieu tinh, lieu tinh, chau tinh
nhanh hung » thanh hung, nhanh hong, nhanh chuong
hanh dung » thanh dung, anh dung, hanh dong
cua nhung » va nhung
dan toan » dan than, manh toan, xuan toan
van toan » van tuan, van tan, van thanh

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: theo chieu tinh - ((nhanh hung) OR (hanh dung)) cua nhung phuong ((dan toan) OR (van toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - ((nhanh hung) or (hanh dung)) cua nhung phuong ((dan toan) OR (van toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - ((nhanh hung) or (hanh dung)) cua nhung phuong ((dan toan) OR (van toan)) cau*.
