Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
ban hanh » ban hang
va thanh » gia thanh, ban thanh, va tinh
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va chat » van chat, va phat, cao chat
va hanh » van hanh, va danh, dao hanh
cua tre » cua te, cuu tre, cua triet
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky nang xa hoi. hieu va chat xuc ((((va hanh) OR (ban hanh))) or (va thanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang xa hoi. hieu va chat xuc ((((va hanh) OR (ban hanh))) OR (va thanh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang xa hoi. hieu va chat xuc ((((va hanh) OR (ban hanh))) or (va thanh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang xa hoi. hieu va chat xuc ((((va hanh) OR (ban hanh))) or (va thanh)) vi cua tre*.
