In the wake of the September 18th Incident, Lin left for Beijing, where she studied ancient Chinese architecture. Upon her return, she helped to establish the Architectural Department at Northeastern University in Shenyang, where she then taught architecture briefly. Meanwhile, in 1928, she designed a railway station in Jilin. This was one of the few buildings Lin designed. Throughout the 1930s, Lin and her husband lived in Beiping, as Beijing was then called, near both of their families. Close friends at the time were the Americans Wilma and John K. Fairbank, who admired her sense of living on a “kind of double cultural frontier,” and facing the problem of “the necessity to winnow the past and discriminate among things foreign, what to preserve and what to borrow.”
