Perhaps you should try some spelling variations:
hieu su » hieu sau, tieu su, hieu so
ky sang » ky nang, ky tang, duy sang
ky dang » ky nang, ky danh
lai roi » lai hoi, loi roi
su chao » su cao, sau chan
xu van » tu van, vu van, su van
vi cua » vai cua, di cua
tu sai » tu bai, tu san, tu cai
cua te » cua tu
xu va » tu va, su va, vu va

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 sai ((ky sang) OR (ky dang)) lai roi. hieu su chao ((xu va) OR (xu van)) hanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ((ky sang) OR (ky dang)) lai roi. hieu su chao ((xu va) or (xu van)) hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sai ((ky sang) OR (ky dang)) lai roi. hieu su chao ((xu va) or (xu van)) hanh vi cua te*.
