If online fortune telling is a superstitious activity, then why should Baidu set up fortune telling?

That depends on how you look at fortune telling.

Who said online fortune-telling superstition? The same thing, some people just have fun and laugh it off, while others take it seriously, depending on their attitude. As long as there is no evil purpose, it is only to satisfy people's desire to know themselves and understand themselves. This is people's thirst for knowledge since ancient times.

Besides, why is it superstition? What people think of seeing is believing is not always correct. In ancient times, people didn't know the existence of oxygen, so they couldn't breathe oxygen. We just don't know how it works.

Of course, those who cheat by fortune telling are another matter.
