Perhaps you should try some spelling variations:
chat huu » pham huu
hieu van » hieu va, thien van, lieu va
chat xuc » cam xuc, chat cua, chat hoc
hanh dao » lanh dao, thanh dat, thanh dam
su sach » so sach, vu sach
dao cua » dai cua, day cua, dan cua
va hanh » van hanh, va thanh, va danh
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 (chat huu))) or (chao xu)) va hanh dao 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 (chat huu))) OR (chao xu)) va hanh dao 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 (chat huu))) or (chao xu)) va hanh dao cua tre*".
