Tan Birong is a short‑haired female student, part of the trio that tries to take the cat. She is practical: she opens a can of goose liver cat food to attract Li Li. She skillfully pets the cat and checks his weight. She later helps to put Li Li into the cage and expresses regret when they are stopped. After the crisis, she suggests informing other feeders. She is calm, observant, and sensible, providing a logical balance to the group.
