Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
su triet » su viet, su tien, ve triet
hieu van » hieu va, thien van, lieu va
va thanh » gia thanh, ban thanh, va tinh
cau thuc » cau truc, cuu thuc, can thuc
vu nang » vuc nang, va nang, vu dang
van cau » van dau, van hau, van chat
thuc va » thuc vat, thuc dan, thuc day
te sach » toc sach
y nang » ky nang, ly nang, may nang
v nang » va nang, van nang, voi nang
hai su » hai vu, lai su, hai so

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) OR (vu nang)))) xa hoi. hieu van cau thuc va thanh hai su triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (((v nang) OR (vu nang)))) xa hoi. hieu van cau thuc va thanh hai su triet~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (((v nang) OR (vu nang)))) xa hoi. hieu van cau thuc va thanh hai su triet*.
