Sizhui approaches the man that he had known as his highly esteemed uncle, the man who raised him well besides Lan Wangji. He approaches at the edge of the pool, put his hands together and makes a respectful bow as a child should greet the elder. He sees him recuperating in one of the hot spas, taking a soak.

He smiles cheerfully back. "Zewu-Jun. Uncle. It's good to see you. You're here as well. If I had known you're here, I would have brought you something sweet."

Even if the young man's birthday, he always have a thought for others.
