Perhaps you should try some spelling variations:
may thoi » gay thoi, may thi, tay thoi
hanh vai » hanh vi, hanh va, hanh tai
sach ky » sac ky, sach y, sach ty
vai cuu » vai cua
va hanh » van hanh, va thanh, va danh
cuu tre » cua tre, cau tren, cau treo
xuc va » duc va, tuc va, luc va
sai ky » sac ky
va cao » va co, va dao, va bao

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 ((sach ky) OR (sai ky)) mang may thoi. hieu ((va cao) OR (va cac)) xuc va hanh vai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sai ky)) mang may thoi. hieu ((va cao) OR (va cac)) xuc va hanh vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sai ky)) mang may thoi. hieu ((va cao) OR (va cac)) xuc va hanh vai cuu tre*.
