Perhaps you should try some spelling variations:
vanh tri » vanh tai, thanh tri, dinh tri
te sach » toc sach
van tri » van tai, van thi, van toi
hieu va » lieu va, hieu qua
ty nang » ky nang, ty xang, ly nang
ty hang » ly hang, ty xang, thi hang
cuu tre » cua tre, cau tren, cau treo
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty nang) or (ty hang)) x hoi. hieu va cam xuc va ((vanh tri) OR (van tri)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ty hang)) x hoi. hieu va cam xuc va ((vanh tri) OR (van tri)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) or (ty hang)) x hoi. hieu va cam xuc va ((vanh tri) OR (van tri)) cuu tre*".
