Perhaps you should try some spelling variations:
hanh doi » thanh doi, hanh noi, hang doi
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
qua cac » cua cac
doi cua » dai cua, hoi cua
y nang » ky nang, ly nang, v nang
luc va » duc va, loc va
tuc va » thuc va, truc va, tuc xa
cua te » cua tu

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: tu sach y nang xa hoi. hieu qua cac ((((luc va) OR (tuc va))) OR (hoc dan)) hanh doi cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu qua cac ((((luc va) or (tuc va))) or (hoc dan)) hanh doi cua te*.
