Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va cham » va chat, va tham
xuc van » luc van, vuc van, thuc van
duc van » duc va, duc tan, duc manh
xuc ban » duc ban, cuc ban, quoc ban
cua tre » cua te, cuu tre, cua triet
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
anh vi » hanh vi, anh va, anh ve
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 sac ky nang xa hoi. hieu va cham ((((xuc van) OR (duc van))) or (xuc ban)) anh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu va cham ((((xuc van) OR (duc van))) OR (xuc ban)) anh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu va cham ((((xuc van) OR (duc van))) or (xuc ban)) anh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu va cham ((((xuc van) OR (duc van))) or (xuc ban)) anh vi cua tre*.
