Wan Chu'er asked with a grin, "What is it?"
Old Man Jiang said, "Just a bit of tea."
Just perfect, Old Man Jiang likes drinking tea, but he can't really tell good tea from bad; it's just a habit formed over decades.
It's likely that the tea gifted by Old Sir Zhong is of good quality, which might be wasted on Old Man Jiang who doesn't know much about tea, akin to a cow chewing on peonies.
However, Wan Chu'er didn't say anything; she just smiled and said, "Thank you, Grandpa, for going through the trouble for me."
Old Sir Zhong waved his hand and said, "Go on, call back if you need anything."
This was clearly meant for Jiang Kechu; don't blame me for being rude if you Jiang Family dare to mistreat Wan Chu'er.
Jiang Kechu awkwardly touched his nose and promised proactively, "Grandpa Zhong, don't worry, I'll take good care of Chuchu."
Mr. Jiang harrumphed.
