Liang Younian learned from He Xin that there was a problem with Xia Miaomiao's midterm architectural copy. He was ready to take time to help Xia Miaomiao solve the problem, so he made an appointment with Xia Miaomiao to meet in the model classroom the next morning. Xia Miaomiao came to the model classroom to see Liang Younian early the next morning. Liang Younian learned that Xia Miaomiao had not eaten breakfast, so he gave Xia Miaomiao a bun. The drawing that Xia Miaomiao drew was the design draft of the Sixiu Building, but there was a serious problem with the proportion of the manuscript paper. Liang Younian took Xia Miaomiao to the Sixiu Building for an on-site survey. Before the two measured, Liang Younian mentioned that the tape measure rebounded terribly, and he asked Xia Miaomiao to be careful. Unexpectedly, there was a problem with Xia Miaomiao's tape measure, so Liang Younian had to use Xia Miaomiao's usual method of shaking the tape measure.
