A pig and a tiger fell into the hole together, and finally only the pig came out. How did this happen?

Maybe the tiger is hungry and has no strength.

1, this problem is only known to pigs. This brain teaser is full of irony and a cold joke.

2. Express an idiom: dress up as a pig and eat a tiger. It is a metaphor for hiding strength and playing dumb, so that opponents can easily win after underestimating their enemies.
