Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
van hanh » van thanh, ban hanh, van anh
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
va hanh » va thanh, va danh, ban hanh
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
vu bac » vu bach, vu ban, xu bac
bac ky » cac ky, ban ky, sac ky
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: vu bac ky nang x hoi. hieu ve cham xuc ((va hanh) or (van hanh)) vi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu bac ky nang x hoi. hieu ve cham xuc ((va hanh) OR (van hanh)) vi ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bac ky nang x hoi. hieu ve cham xuc ((va hanh) or (van hanh)) vi ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: vu bac ky nang x hoi. hieu ve cham xuc ((va hanh) or (van hanh)) vi ((cua tre) OR (cuu tre))*.
