Perhaps you should try some spelling variations:
nang sinh » dang sinh, nang kinh, khang sinh
ban nang » ban hang, van nang, ban dang
sinh cuu » dinh cuu, sinh cua, sinh cau
ky lang » ky dang, ky tang, tay lang
cam duc » cam xuc, cao duc, pham duc
duc ban » duc tan, duc van, dua ban
cuu tre » cua tre, cau tren, cau treo
te cac » tu cac, ve cac, te cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: te cac ((ky lang) OR (ky nang)) xa hoi. ((lieu va) or (hieu qua)) cam duc ban nang sinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ((ky lang) OR (ky nang)) xa hoi. ((lieu va) OR (hieu qua)) cam duc ban nang sinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ((ky lang) OR (ky nang)) xa hoi. ((lieu va) or (hieu qua)) cam duc ban nang sinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: te cac ((ky lang) OR (ky nang)) xa hoi. ((lieu va) or (hieu qua)) cam duc ban nang sinh cuu tre*.
