The eager and straightforward Tiemu scratched his head, saying, "You can just call me Tiemu!"
Su Tang was also feeling anxious inside. She wanted to call him 'big brother' as a sign of closeness, but she was rejected!
Could it be... that he is actually younger than her?
Su Tang didn't dare to ask or speak, so she could only clumsily nod her head, "OK! Tiemu!"
...
After the two had walked away, Bu Sen jumped to Aunt Hongguo's side and grumbled, "Aunt Hongguo, you should have sent me to protect Su Tang. That silly beast Tiemu will certainly scare her!"
Aunt Hongguo glanced at Bu Sen and ignored him, continuing to pick chestnuts off the ground.
Bu Sen kept following her, "Aunt Hongguo, you're not unaware of Tiemu's disposition. What if it makes Su Tang think we're all as difficult to get along with as Tiemu? What do we do then?"
Unable to hold it in any longer, Aunt Hongguo gave Bu Sen a heavy slap on the shoulder - his head was too tall to reach!
