Perhaps you should try some spelling variations:
phat xuc » chat xuc, phat xuat, phap xu
van hanh » van thanh, ban hanh, van anh
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
xuc van » duc van, luc van, vuc van
vai cua » dai cua, hai cua, lai cua
di cua » dai cua, doi cua, de cua

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: tu sach ky nang xa hoi. hieu va phat xuc van hanh ((((vi cua) OR (di cua))) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu va phat xuc van hanh ((((vi cua) OR (di cua))) or (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. hieu va phat xuc van hanh ((((vi cua) OR (di cua))) or (vai cua)) tre*.
