Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
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 » hieu qua
xuc van » duc van, luc van, vuc van
van anh » van thanh, tuan anh, van minh
vai cua » dai cua, hai cua, lai cua
vi cua » di 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) OR (lieu va)) chat xuc van anh ((vi 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) OR (lieu va)) chat xuc van anh ((vi cua) or (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. ((hieu va) OR (lieu va)) chat xuc van anh ((vi cua) or (vai cua)) tre*.
