Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van tuan » van quan, van ban, anh tuan
tuan cua » quan cua, than cua, tan cua
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
truc va » thuc vat, trung va
thuc va » thuc vat, thuc dan, thuc day
y nang » ky nang, ly nang, v nang
va cau » van cau, va cac, va dau

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. lieu va cau ((truc va) OR (thuc va)) van tuan cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. lieu va cau ((truc va) or (thuc va)) van tuan cua triet*.
