Perhaps you should try some spelling variations:
so sach » bo sach, co sach, hoc sach
so sanh » do sanh
nang xa » nang x, lang xa, nang ma
ve pham » vi pham, v pham, ve phat
ve phan » va phan, ke phan, ve phat
va hanh » van hanh, va thanh, va danh
vi cua » vai cua, di cua
cua te » cua tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) or (so sanh)) ky nang xa hoi. hieu ((ve pham) OR (ve phan)) duc va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) ky nang xa hoi. hieu ((ve pham) OR (ve phan)) duc va hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (so sanh)) ky nang xa hoi. hieu ((ve pham) OR (ve phan)) duc va hanh vi cua te*".
