Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
van cham » van chat, van tham, va cham
hieu van » hieu va, thien van, lieu va
vai cuu » vai cua
va daoh » va danh, va doanh
tu sach » thu sach, su sach, te sach
ty nang » ky nang, ty hang, ly nang
cuu tre » cua tre, cau tren, cau treo
va dao » ca dao

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

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