Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
viec dai » vien dai, viec tai, viec dang
viec dat » vien dai, vien da, viec lam
thuc cao » thuoc cao, thuc co, thuc can
dang vai » dang van, dang vat, dang va
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
vai cua » dai cua, hai cua, lai cua

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 ty nang xa hoi. nhieu ((viec dai) OR (viec dat)) thuc cao dang vai cua triet~.
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. nhieu ((viec dai) or (viec dat)) thuc cao dang vai cua triet*.
