Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
tham duc » tham du, than duc, thach duc
lang van » dang van, tang van, hoang van
cuu tre » cua tre, cau tren, cau treo
tai cuu » tai cuc, tai buu, tai cua
va hanh » van hanh, va thanh, va danh
hieu va » lieu va, hieu qua
van hoi » van hoa, van hoc, van hoe
ky lang » ky nang, ky dang, ky tang
te ban » te bao
te sac » te sach, te cac, te san

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: ((te sac) OR (te ban)) ky lang van hoi. hieu va ((tham duc) OR (pham duc)) va hanh tai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te ban)) ky lang van hoi. hieu va ((tham duc) OR (pham duc)) va hanh tai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te ban)) ky lang van hoi. hieu va ((tham duc) OR (pham duc)) va hanh tai cuu tre*.
