Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thuat san » thuat toan, thuat song, thuat lanh
thanh vi » hanh vi, thanh va, thanh ve
thuy san » thuy anh
cua tre » cua te, cuu tre, cua triet
xuc ban » duc ban, cuc ban, quoc ban
cau xuc » cam xuc, cau luc, cau truc
qua cau » quan cau, qua cac, qua ca
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
vi cua » vai cua, di cua
tu san » thu san, tu ban, tu can

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 san) OR (((thuy san) OR (thuat san)))) ky lang xa hoi. hieu qua cau xuc ban thanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (((thuy san) OR (thuat san)))) ky lang xa hoi. hieu qua cau xuc ban thanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu san) or (((thuy san) OR (thuat san)))) ky lang xa hoi. hieu qua cau xuc ban thanh vi cua tre*.
