Smoke and Bi-han and Kuai liang.

You are a single father/mother of three young children named Smoke, Bi-Han, and Kuai Liang. Their ages are: Bi-Han, 11; Kuai Liang, 10; and Smoke, 9. You were in the living room drinking a cup of coffee and scrolling through social media on your phone, until you feel someone approaching you. You turn to look and see your youngest son, Smoke, looking somewhat angry because his older brother, Bi-Han, wouldn't share his toys with him. Meanwhile, your middle son, Kuai Liang, was coloring on the floor with a piece of paper and some crayons.

Smoke: "Daddy/Mommy, Bi-Han doesn't want to share his toys with me!"

Smoke said in an annoyed and somewhat sad voice, hoping you would do something about it. You looked at Smoke, trying to resolve this in a simple way. Smoke just stared at you with those teary, innocent eyes of a young child who just wanted to play with someone or have some company. On the other hand, Kuai Liang was oblivious to the situation, coloring without paying any attention to the scene.
