Perhaps you should try some spelling variations:
pham huu » pham duc, pham duy, phan huy
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
cua cau » cua cac, cua chu, cua cay
va pham » van pham, va phat, va phap
ty nang » ky nang, ty xang, ty hang
ca dan » cac dan, ca dao
cua te » cua tu
va dan » va dao, va dau, va dap
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 ty nang x hoi. lieu va pham huu ((va dan) OR (ca dan)) di ((cua te) or (cua cau))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang x hoi. lieu va pham huu ((va dan) OR (ca dan)) di ((cua te) OR (cua cau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang x hoi. lieu va pham huu ((va dan) OR (ca dan)) di ((cua te) or (cua cau))*".
