Perhaps you should try some spelling variations:

thanh dam » thanh dat, thanh nam, thanh lam
hieu van » hieu va, thien van, lieu va
chat xuc » chat huu, cam xuc, chat cua
su sach » so sach, vu sach
cua tre » cua te, cuu tre, cua triet
sach ky » sac ky, sach y, sach ty
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: su sach ky nang x hoi. hieu van ((chat xuc) or (chao xu)) va ((thanh dam) OR (thanh tam)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang x hoi. hieu van ((chat xuc) OR (chao xu)) va ((thanh dam) OR (thanh tam)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang x hoi. hieu van ((chat xuc) or (chao xu)) va ((thanh dam) OR (thanh tam)) cua tre*".
