Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
quang tuan » quang thanh, quan luan
hien xanh » hien hanh, hien nhanh, chieu xanh
quang cua » quan cua, quang huy, dung cua
manh toan » thanh toan, anh tuan, tinh toan
dan toan » van toan, dan than, xuan toan

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 hien xanh - nhanh ((quang cua) OR (quang tuan)) nhung phuong ((dan toan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - nhanh ((quang cua) or (quang tuan)) nhung phuong ((dan toan) OR (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - nhanh ((quang cua) or (quang tuan)) nhung phuong ((dan toan) OR (manh toan)) cau*.
