In a letter to her daughter Liang Zaibing, in 1937, architect Lin Huiyin described the hardships during her fourth trip with Liang Sicheng from Beijing to Shanxi province. At the end of the letter, she drew two maps, one showing the places en route to their destination and another of Hebei and Shanxi provinces, detailing the railways, sections of the Great Wall and the modes of transport they took: horse riding, public bus and mules. The touching six-page letter impressed many when it was on show at an exhibition commemorating the 120th anniversary of Liang Sicheng's birth two years ago, at Tsinghua University Art Museum. It has now been added to Sincerely Yours, an ongoing exhibition mounted by the museum to show personal letters from scholars of Tsinghua University, like the one Lin, who once taught architecture there, wrote. The exhibition was first presented in 2019 and was widely praised. It shows the cultural accumulations, rich emotions and temperaments of the featured intellectuals, as well as their fine writing, some of which pieces are considered excellent examples of calligraphy. The long-term exhibition runs until May 2024.
