Perhaps you should try some spelling variations:
duc manh » suc manh, duc anh, duc minh
hanh dao » lanh dao, thanh dat, thanh dam
hanh dai » hanh tai, vanh dai, thanh dat
cua tre » cua te, cuu tre, cua triet
xuc van » duc van, luc van, vuc van
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
tang ha » lang ha, tang ma, trung ha
ky tang » ky nang, ky dang, kho tang
bai ky » ban ky, sai ky, bac ky
tu bai » tu ban, tu bat, te bai

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 bai ky tang ha noi. hieu ve chat ((xuc van) OR (duc manh)) ((hanh dai) OR (hanh dao)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bai ky tang ha noi. hieu ve chat ((xuc van) or (duc manh)) ((hanh dai) OR (hanh dao)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu bai ky tang ha noi. hieu ve chat ((xuc van) or (duc manh)) ((hanh dai) OR (hanh dao)) cua tre*.
