Why didn't Lin finally choose Xu Zhimo?

Lin was taken to England by her father when she was a girl. Instead of indulging in feasting and amusement, the clever boy noticed that there was a learning in Britain, that is, architecture, and Lin was immediately fascinated by architecture. Architecture is an academic major that China has never had before. Lin was determined to bring the building back to China, which became the ambition of young Lin.

After returning to China, Lin told Liang Sicheng that he didn't even know what a building was. Liang Sicheng fully accepted Lin's suggestion, and from then on, he took architectural creation in China as his lifelong career. Both of them came to the United States to study architecture, but the college with architecture that Liang Sicheng entered did not accept girls. Lin had to go to the nearby Academy of Fine Arts, but she still worked as an art teacher in the architectural school. In the end, both of them got good grades. After graduation, I went to Europe to visit and inspect architecture, which deepened my understanding of classical architecture and modern architecture. After returning to China, he founded the Department of Architecture of Northeastern University to train architectural talents.

Later, he went to the Construction Society sponsored by Zhu Qiqian to do research. Because there are no buildings in China since ancient times, and the ancient buildings in China are unique in the world, all the research starts with the basic information of the ancient buildings in China. On the one hand, they translate and annotate ancient books, compile building rules and examples, and on the other hand, they inspect the remains of ancient buildings on the spot, among which Lin is also diligent. Xu Zhimo also pursues Lin, but his sour love is not suitable for Lin's ideal. It is also impossible for Xu Zhimo to introduce architecture and realize Lin's expectations, but to travel across mountains and rivers, to get bitten by mosquitoes and to collect information on ancient buildings. In the end, Lin resolutely rejected him.
