Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hanh di » hanh vi, hanh de, hang di
xuc van » duc van, luc van, xuc ban
va cam » va cham, va cac, va cao
di cua » dai cua, doi cua, de cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cai, ve cau
ve cac » va cac, vien cac

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