Where was the 86th edition of Journey to the West taken by the Monkey King in the belly of Princess Iron Fan?

At that time, the artist made two semi-circular models similar to the shape of the stomach. Then fill it with sponge, decorate it with color-changing lights, and let the six-year-old playing the Monkey King in. In order to make the effect realistic, people keep pushing the model outside, creating a feeling of peristalsis like a stomach, and then presenting the effect on TV.
