Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
van chat » cao chat
va thanh » gia thanh, ban thanh, va tinh
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, tuc xa
x hoi » xa hoi, o hoi, x ho

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: te ((sac ky) OR (sai ky)) nang x hoi. hieu ((va cam) OR (van chat)) tuc va thanh dai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) nang x hoi. hieu ((va cam) or (van chat)) tuc va thanh dai cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (sai ky)) nang x hoi. hieu ((va cam) or (van chat)) tuc va thanh dai cua tre*.
