Perhaps you should try some spelling variations:
bao xuc » bao luc, bao thuc
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
su cac » tu cac, su cao, su can
va bao » va bai
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 cac ky nang x hoi. lieu va bao xuc ((va hanh) OR (va danh)) trinh ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac ky nang x hoi. lieu va bao xuc ((va hanh) OR (va danh)) trinh ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ky nang x hoi. lieu va bao xuc ((va hanh) OR (va danh)) trinh ((cua tre) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: su cac ky nang x hoi. lieu va bao xuc ((va hanh) OR (va danh)) trinh ((cua tre) or (cuu tre))*.
