Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
toc sach » hoc sach, thuoc sach, nuoc sach
va thanh » gia thanh, ban thanh, va tinh
cua viet » ca viet, hoa viet, cua vat
doc sach » hoc sach, nuoc sach, dac sac
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
van hac » van hoc, van ha, van hai
lap cua » lai cua, tap cua, lam cua
van bac » van ban, van bao, dan bac
luc va » duc va, tuc va, loc va

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) OR (doc sach)) ty nang xa hoi. thi ((van bac) OR (van hac)) luc va thanh lap cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (doc sach)) ty nang xa hoi. thi ((van bac) or (van hac)) luc va thanh lap cua viet~".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) OR (doc sach)) ty nang xa hoi. thi ((van bac) or (van hac)) luc va thanh lap cua viet*.
