Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
thanh do » thanh de, thanh pho, thanh hoa
cua tre » cua te, cuu tre, cua triet
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, xuc ban
va cham » va chat, va tham
do cua » doi cua, co cua, de cua
tu sac » tu cac, tu san, tu bac
ve cam » ve cham, ve cac, va cam

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 sac) OR (tu sach)) ky nang xa hoi. hieu ((ve cam) OR (va cham)) xuc van thanh do cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky nang xa hoi. hieu ((ve cam) or (va cham)) xuc van thanh do cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu sach)) ky nang xa hoi. hieu ((ve cam) or (va cham)) xuc van thanh do cua tre*.
