Perhaps you should try some spelling variations:
hieu sau » hieu su, hieu suat, tieu su
sau chao » sau cho, sau chan, cau cham
ky sang » ky nang, ky dang, duy sang
ky tang » ky nang, ky dang, kho tang
lai roi » lai hoi, loi roi
tu san » thu san, tu ban, tu can
vi cua » vai cua, di cua
cua te » cua tu
xu va » xu van, su va, vu va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu san ((ky sang) OR (ky tang)) lai roi. hieu sau chao ((xu va) or (tu va)) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ((ky sang) OR (ky tang)) lai roi. hieu sau chao ((xu va) OR (tu va)) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ((ky sang) OR (ky tang)) lai roi. hieu sau chao ((xu va) or (tu va)) hanh vi cua te*".
