Perhaps you should try some spelling variations:
sang lai » sang tai, sang lap, mang lai
hanh vai » hanh vi, hanh va, hanh tai
hieu va » lieu va, hieu qua
ky sang » ky nang, ky dang, ky tang
lai hoa » dai hoa, loai hoc
hieu so » thieu so
vai cua » dai cua, hai cua, lai cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky sang lai hoa. ((hieu so) OR (hieu va)) chao ((xu va) OR (tu va)) hanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky sang lai hoa. ((hieu so) or (hieu va)) chao ((xu va) OR (tu va)) hanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky sang lai hoa. ((hieu so) or (hieu va)) chao ((xu va) OR (tu va)) hanh vai cua te*.
