hieu va » lieu va
cam tuc » cam xuc, cam tu, nam thuc
va tinh » may tinh
hoi cuu » hoi chu, hoi cua, ho cuu
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ma hoi. ((hieu va) OR (hieu qua)) cam tuc ((va tinh) or (gia thanh)) hoi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. ((hieu va) OR (hieu qua)) cam tuc ((va tinh) OR (gia thanh)) hoi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. ((hieu va) OR (hieu qua)) cam tuc ((va tinh) or (gia thanh)) hoi cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. ((hieu va) OR (hieu qua)) cam tuc ((va tinh) or (gia thanh)) hoi cuu tre*.
