Perhaps you should try some spelling variations:
thanh van » thanh san, thanh toan, thanh phan
ban thanh » ban hanh, ban hang
thien van » thi van
tu sach » thu sach, su sach, te sach
cay dua » chay dua, cay lua, ca dua
cua tre » cua te, cua triet, dua tren
dua ban » dia ban, cua ban, qua ban
van cay » van cau, van bay, van ca
ty hang » ly hang, ty xang, thi hang
ty dang » ty xang, ky dang, ty dong
cuu tre » cau tren, cau treo

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 sach ((ty dang) OR (ty hang)) ma hoa. thien van cay dua ban thanh van ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty dang) or (ty hang)) ma hoa. thien van cay dua ban thanh van ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty dang) or (ty hang)) ma hoa. thien van cay dua ban thanh van ((cua tre) OR (cuu tre))*.
