Perhaps you should try some spelling variations:
pham thuc » phap thuc, pham chuc, nham thuc
toc sach » hoc sach, doc sach, thuoc sach
va doanh » van doanh, vay doanh, va danh
hieu vu » hieu va, hieu ve, hieu su
vu pham » su pham, vi pham, vu kham
nang xa » nang x, lang xa, nang ma
sach ky » sac ky, sach y, sach ty
day cua » dai cua
cua tre » cua te, cuu tre, cua triet
va dan » ca dan, va dau, va dap
va dao » ca dao

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: toc sach ky nang xa hoi. hieu vu pham thuc ((va doanh) OR (((va dan) OR (va dao)))) day cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky nang xa hoi. hieu vu pham thuc ((va doanh) or (((va dan) OR (va dao)))) day cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach ky nang xa hoi. hieu vu pham thuc ((va doanh) or (((va dan) OR (va dao)))) day cua tre*.
