Perhaps you should try some spelling variations:
nhung phuong » dung phuong, truong phuong, bang phuong
hoan chinh » hanh chinh, hoa hinh
manh trung » manh tung, thanh trung, manh hung
nhu phuong » thu phuong, thi phuong, thu huong
hoc chinh » hoc sinh, hoc kinh
trung vap » trung cap, trung va, trung van
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

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 chinh) OR (hoan chinh)) sach - manh trung vap ((nhung phuong) OR (nhu phuong)) dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chinh) OR (hoan chinh)) sach - manh trung vap ((nhung phuong) or (nhu phuong)) dan than cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chinh) OR (hoan chinh)) sach - manh trung vap ((nhung phuong) or (nhu phuong)) dan than cau*.
