nang xa » nang x, lang xa, nang ma
thi van » thi lan, thi hanh, thi nang
lam xuc » cam xuc, lam duoc
xuc gia » duc gia, luc gia, tuc gia
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
de cuu » de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (tu sach)) y nang xa hoi. ((thien van) or (thi van)) lam xuc gia thanh de cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) y nang xa hoi. ((thien van) OR (thi van)) lam xuc gia thanh de cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) y nang xa hoi. ((thien van) or (thi van)) lam xuc gia thanh de cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) OR (tu sach)) y nang xa hoi. ((thien van) or (thi van)) lam xuc gia thanh de cuu tre*.
