Perhaps you should try some spelling variations:
su sach » so sach, vu sach
ve pham » v pham, ve phan, le pham
ve phat » va phat, te phat, de phat
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang
vi cua » vai cua, di cua
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

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