Perhaps you should try some spelling variations:
cham xuc » cam xuc, cham soc, pham duc
hoc sach » hoc sinh, hoc cac, hoc anh
chat xuc » chat huu, cam xuc, chao xu
tai cuu » tai cuc, tai buu, tai cua
han tai » hang tai, nhan tai, van tai
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
cuu tre » cua tre, cau tren, cau treo
va han » va phan, van han, va hanh

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) or (hoc sach)) ky nang xa hoi. lieu va ((cham xuc) OR (chat xuc)) va han tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (hoc sach)) ky nang xa hoi. lieu va ((cham xuc) OR (chat xuc)) va han tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (hoc sach)) ky nang xa hoi. lieu va ((cham xuc) OR (chat xuc)) va han tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (hoc sach)) ky nang xa hoi. lieu va ((cham xuc) OR (chat xuc)) va han tai cuu tre*.
