Quick question ~ ~: What episode is the story of Bai Wen (second grandma) picking up a plaque at the mansion gate?

My uncle's daughter,/kloc-Bai, aged 0/6, married in Jinan, Shandong. Seven-year-old Bai Jingqi was so stubborn that she left three teachers in succession. The angry second grandma looked for a good teacher everywhere, but no one dared to come. When Zhan heard that grandpa was not dead, he complained everywhere and his whereabouts were unknown. Grandma Wang finally decided to take off the plaque of "Bai Jia Lao Hao" in order to return to the "Baicaotang". If she hadn't asked for it, she would have become a shareholder with the old plaque. Unexpectedly, Dong Daxing asked Grandma Wang to pick the plaque, but the second grandma couldn't, and began to use the line of the father-in-law in the palace. Father-in-law Chang began to attack Dong Daxing, and wanted to exempt the palace of "Baicaotang" on the grounds that the pharmacy was not good. The third young master had no choice but to steal the secret recipe from Bai Wen's room, and Bai Wen was caught red-handed.
