Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
va thanh » gia thanh, ban thanh, va tinh
sang tai » hang tai, sang tao, tang tai
van lam » van nam
vai cua » dai cua, hai cua, lai cua
tai hoi » tai khoi, dai hoi, tai hai
cua tre » cua te, cuu tre, cua triet
va lam » va lap

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: phu ((van ky) OR (dan ky)) sang tai hoi. hieu ((va lam) OR (van lam)) duc va thanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "phu ((van ky) or (dan ky)) sang tai hoi. hieu ((va lam) OR (van lam)) duc va thanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: phu ((van ky) or (dan ky)) sang tai hoi. hieu ((va lam) OR (van lam)) duc va thanh vai cua tre*.
