Because they didn't know whether the old man was a friend or an enemy, Leng Shaoting and Gu Ning disguised themselves as Qing Feng and Qing He in order to avoid meeting the old man.
Lao Zhang left after making the meal, so Stone was the only mortal left in the house. Given the current situation, Leng Shaoting needed him to leave, so he told Stone to take a few days off.
Jing Yunyao and Miao Jingjing went directly back to their rooms. If the old man came in, they wouldn't appear.
The old man had no malice for the people in the siheyuan, but he was very curious to know who was living there. Therefore, the old man decided to pay them a visit.
Although it was an abrupt visit, he was unwilling to leave without figuring out who was living there. If there were familiar faces, it wouldn't be impolite.
Accordingly, the old man walked to the front gate of the siheyuan and knocked on it.
