Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
cuu tre » cua tre, cau tren, cau treo
dinh vi » dinh ve, dinh viet, dinh tri
va cham » va chat, va tham
nang ma » tang ma, sang ma, nang cao
ma hoi » mai hoi, xa hoi, ma hoa
san ky » sang ky, van ky, ban ky
dan ky » van ky
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((san ky) OR (dan ky)) nang ma hoi. lieu va cham xuc va ((dinh vi) or (hanh vi)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (dan ky)) nang ma hoi. lieu va cham xuc va ((dinh vi) OR (hanh vi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) OR (dan ky)) nang ma hoi. lieu va cham xuc va ((dinh vi) or (hanh vi)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) OR (dan ky)) nang ma hoi. lieu va cham xuc va ((dinh vi) or (hanh vi)) cuu tre*.
