Finding a childhood trauma

I saw this on TV. The plot is as follows: It starts with a residential garden setting, where a group of children are playing tag (Eagle Catches Chick). The scene shifts to the kitchen, where a woman in a green qipao asks the maid where the young master is. The maid replies he is studying upstairs, praising the young master for being steady. On the second floor, a little boy in overalls closes his book and goes to the window to watch the children playing downstairs. He secretly goes downstairs and joins the end of the game line. When the uncle playing the eagle scares the children, the latter half of the children fall into a lake. After being rescued ashore, the originally second-to-last chubby boy says there's only one girl behind him, and the last girl retorts that there's someone behind her. The scene shifts to under an arched bridge, where a young master, only his head showing, stands in the water with his back to the camera. Then the TV was turned off. It was the first time I saw my mom run so fast 🤣🤣
