Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh tai, hanh van
cua tre » cua te, cua triet, dua tren
hanh va » hang va, hanh vi
sach ty » sach y, sach tu, sach thu
so sach » so sanh, bo sach, co sach
xuc van » duc van, luc van, vuc van
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
cuu tre » cau tren, cau treo
va cam » va cham, va cac, va cao

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

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