Perhaps you should try some spelling variations:
hanh dao » thanh dat, thanh dam, doanh dao
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
cua tre » cua te, cuu tre, cua triet
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
tang ha » lang ha, tang ma, trung ha
ky tang » ky nang, ky dang, kho tang
sai ky » sac ky
ha hoi » hoa hoi, ha noi, xa hoi
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 tang ha hoi. hieu ve cham ((xuc van) OR (duc van)) ((hanh dao) OR (lanh dao)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky tang ha hoi. hieu ve cham ((xuc van) or (duc van)) ((hanh dao) OR (lanh dao)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sai ky tang ha hoi. hieu ve cham ((xuc van) or (duc van)) ((hanh dao) OR (lanh dao)) cua tre*.
