Perhaps you should try some spelling variations:
gianh lai » gian lan
hieu van » hieu va, thien van, lieu va
va gianh » va gian, van giang, va giai
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va
dao duc » giao duc, tao duoc
lai cuu » lai cua, lai chau, lai cuoc
cuu tre » cua tre, cau tren, cau treo
te sac » te sach, te san
te cac » tu cac, ve cac, te cao

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te cac)) ky nang xa hoi. ((hieu ve) OR (hieu van)) dao duc va gianh lai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te cac)) ky nang xa hoi. ((hieu ve) or (hieu van)) dao duc va gianh lai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te cac)) ky nang xa hoi. ((hieu ve) or (hieu van)) dao duc va gianh lai cuu tre*.
