Chapter 69
"Flowers in the Mirror" tells the story of a talented woman Milan Finn counting the light ball——

Once Miranfen came to a rich man's house, and the owner invited her to watch the colorful, high and low light balls in the hall downstairs, which looked like stars.

The owner told her: "There are two kinds of lights downstairs: one is a big ball under the lamp, and two small balls are attached to it; the other is a big ball under the lamp, and four small balls are attached to it. There are 360 ​​balls in total, and 1200 small light balls."

The master asked her to count how many of the two kinds of lamps there were.

[Answer: One big light ball with two small light balls under it is a chicken, and one big light ball with four small light balls under it is a rabbit.

（360×4-1200）÷（4-2）=240÷2=120（一大二小灯的盏数）
360-120=240 (the number of one big and four small lights)]
