Perhaps you should try some spelling variations:
tang lai » trang lai, tang tai, tang loi
hieu su » hieu sau, tieu su, hieu so
tu sach » thu sach, su sach, te sach
ky tang » ky nang, ky dang, kho tang
lai hoi » dai hoi, lai hoa, lai roi
su chao » su cao, sau chan
xu van » tu van, vu van, su van
vi cua » vai cua, di cua
tu sac » tu cac, tu san, tu bac
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 sac) OR (tu sach)) ky tang lai hoi. 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 sac) or (tu sach)) ky tang lai hoi. hieu su chao ((xu va) OR (xu van)) hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) or (tu sach)) ky tang lai hoi. hieu su chao ((xu va) OR (xu van)) hanh vi cua te*.
