Perhaps you should try some spelling variations:
te sach » toc sach
sach ty » sach y, sach tu, sach thu
va tinh » may tinh
vu dinh » quy dinh
cac dac » cac dan, cac dai, cac bac
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ty nang » ky nang, ty xang, ty hang
vi cua » vai cua, di cua
cua tu » cua tuc, cua su, cua cu

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. ((hieu ve) OR (lieu va)) cac dac ((vu dinh) OR (va tinh)) vi cua tu~.
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. ((hieu ve) or (lieu va)) cac dac ((vu dinh) or (va tinh)) vi cua tu*.
