Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
chat xuc » chat huu, cam xuc, chat cua
hanh hoi » hanh thoi, hanh noi, hanh hoa
su sach » so sach, vu sach
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
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 y nang x hoi. hieu van ((chat xuc) OR (chao xu)) va hanh hoi ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang x hoi. hieu van ((chat xuc) OR (chao xu)) va hanh hoi ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang x hoi. hieu van ((chat xuc) OR (chao xu)) va hanh hoi ((cua tre) or (cuu tre))*".
