Perhaps you should try some spelling variations:
thien van » thi van
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
van cau » van dau, van hau, van chat
cau luc » cau truc, cau phuc
ba benh » va benh, bo benh, bach benh
y nang » ky nang, ly nang, v nang
luc ba » luc bat, luc va, luc ha
vi cua » vai cua
di cua » doi cua, de cua, do 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: so sach y nang xa hoi. thien van cau luc ba benh ((((vi cua) OR (dai cua))) OR (di cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: so sach y nang xa hoi. thien van cau luc ba benh ((((vi cua) or (dai cua))) or (di cua)) tre*.
