Zhulan inquired about the Zheng family solely because of Lady Zheng. It was through their frequent interactions that Zhulan discovered Lady Zheng was a hidden master. Astounded after receiving pointers from Lady Zheng on her painting, Zhulan had never imagined the homebound Lady Zheng to be an expert in painting - one's expertise was clear from the moment they started.
Lady Zheng must have been trained from a young age. Zhulan had never really paid much attention to Lady Zheng, mainly because she kept to herself, and before Zhou Shuxi moved over, Zhulan barely got to see Lady Zheng.
Lady Zheng's maiden home was in Li Family Village. When Zhulan mentioned this to Zhou Shuren, he took note of it and thus began his inquiries.
Zhulan did want Lady Li to go back to her maiden home to ask around, but she feared Lady Li couldn't keep a secret. It wasn't that Zhulan was curious about Lady Zheng; she was just used to thoroughly understanding the unknown to avoid unnecessary troubles.
