Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
hanh di » hanh vi, hanh de, hang di
duc van » duc va, duc tan, duc manh
xuc van » luc van, vuc van, xuc ban
hieu va » lieu va, hieu qua
hieu ve » hieu van
lang ha » long ha
ky lang » ky nang, ky dang, ky tang
sai ky » sac ky
di cua » dai cua, doi cua, de cua
tu sai » tu bai, tu san, tu cai

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 lang ha noi. ((hieu ve) OR (hieu va)) cham ((xuc van) OR (duc van)) hanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky lang ha noi. ((hieu ve) OR (hieu va)) cham ((xuc van) or (duc van)) hanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sai ky lang ha noi. ((hieu ve) OR (hieu va)) cham ((xuc van) or (duc van)) hanh di cua tre*.
