Perhaps you should try some spelling variations:
dinh sinh » tinh sinh, dinh kinh, dinh tinh
sinh cua » manh cua, dinh cuu, sinh va
cua tre » cua te, cuu tre, cua triet
va tham » van tham, va cham, va thanh
va dinh » van dinh, va kinh, va tinh
ve chat » va chat, van chat
ve cham » va cham, vu cham, ve chim
lang ha » long ha
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu san

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 ha noi. hieu ((((ve cham) OR (ve chat))) OR (va tham)) hoc va dinh sinh cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang ha noi. hieu ((((ve cham) OR (ve chat))) or (va tham)) hoc va dinh sinh cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang ha noi. hieu ((((ve cham) OR (ve chat))) or (va tham)) hoc va dinh sinh cua tre*.
