The Hongqi CA770 took shape through seven clay proposals, factory-wide review and a full-size model made under difficult workshop conditions. Jia Yanliang and Wang Zhen recall different parts of the design, while a later university-published design-history review places the sedan programme and its delivery milestones in a longer chronology.
The Jiefang CA10 emerged from overseas training, Soviet technical assistance and factory adjustment. A 1956 newspaper report follows ten trial trucks from the moving line to engineering inspection, while FAW’s technical history records the later drive to improve the model for Chinese use.
Jingyuetan began as a 1934 water-supply reservoir beside a deliberately planted watershed. Recent reports describe shoreline repair and ecological sampling at the lake.
Xinmin Street’s former State Council building embodied a Japanese-backed administration before becoming a medical teaching building. Its 2025 renewal connected courtyards and pocket parks to everyday walking routes while the avenue kept its university, hospital and museum uses.
Puyi’s former palace arranged authority across a reused salt office, private quarters and halls that combined political work and leisure. The complex’s rooms reveal how a Japanese-backed regime staged its court in Changchun.
The Northeast Film Studio’s 1949 Chinese-language version of The Ordinary Soldier required translators and performers to fit spoken Chinese into the moving image. A stopwatch helped expose the timing mismatch; revised wording and delivery made the scene speak naturally.
The Bridge turned railway factory work into a film story, then used Changchun studio space to stage a broken bridge at miniature scale. Its production links an inherited film campus to a postwar crew building new methods.
