Perhaps you should try some spelling variations:
cham luc » cham soc, nhan luc, cham cuu
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
cua cua » cua chua, qua cua, cua cha
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
va dau » va dao
ca cua » co cua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu vu cham luc va dau ((cua cua) OR (ca cua)) vat~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu vu cham luc va dau ((cua cua) OR (ca cua)) vat*.
