What's the difference between a stupa and a pagoda?

Amitabha! The difference between stupa and stupa is that the former does not provide sightseeing, but it is a stupa for placing ashes in a temple. Which master died in the temple? As for the stupa after incineration, because there is a saying in Buddhism that the master died and was called the relic after incineration, the stupa came. The stupa is for pilgrims and tourists, and there is nothing in it!
