Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cham xuc » cam xuc, chat xuc, cham soc
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va cham » va chat, va tham
va hanh » van hanh, va thanh, va danh
cua tre » cua te, dua tren, cua thep
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

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

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