Perhaps you should try some spelling variations:
nhan luc » nang luc
thai cua » than cua, tai cuc, tri cua
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
hai cua » dai cua, hoi cua, lai cua
ve nhan » ve nha, de nhan, va nhan
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, may nang
luc va » duc va, tuc va, loc va
v nang » va nang, vu nang, van nang

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 sach ((y nang) OR (v nang)) xa hoi. hieu ve nhan luc va thanh ((hai cua) OR (thai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (v nang)) xa hoi. hieu ve nhan luc va thanh ((hai cua) OR (thai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (v nang)) xa hoi. hieu ve nhan luc va thanh ((hai cua) OR (thai cua)) tre*.
