Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
toc sach » hoc sach, doc sach, thuoc sach
hieu van » hieu va, thien van, lieu va
van chat » cao chat
chat xuc » chat huu, cam xuc, chao xu
ky danh » ky anh, ky dang
don vai » don vi, don va, den vai
cua tre » cua te, cuu tre, dua tren
xuc va » duc va, tuc va, luc va
va don » va dong, va doc, va do

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: toc sach ((ky danh) OR (ky nang)) xa hoi. hieu van chat xuc va don vai ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((ky danh) or (ky nang)) xa hoi. hieu van chat xuc va don vai ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: toc sach ((ky danh) or (ky nang)) xa hoi. hieu van chat xuc va don vai ((cua tre) OR (cua triet))*.
