Caigentan is a type of food that comes from China. It's often eaten for breakfast, but it can be eaten anytime of the day. Caigentan is made from rice that has been cooked and then mixed with eggs, meat, vegetables, and different flavorings like soy sauce or sesame oil.
Imagine you're making oatmeal for breakfast, but instead of adding just plain water, you add different yummy things like bacon, carrots, and maybe even some cheese! That's pretty much what caigentan is like - rice mixed with different ingredients to make it extra delicious.
Some people also call caigentan "fried rice omelet" because it looks like an omelet with rice in it. It's a popular dish in China, and if you ever get a chance to try it, you might really like it!
