Start with Shen Cafe at Shangri-La Changchun and Museum of the Imperial Palace of Manchukuo
Use one real cafe and one real sight.
- Start at the cafe
- Move to the sight
- keep the next stops close enough to make sense
Start the day with Shen Cafe at Shangri-La Changchun at 569 Xian Road, Chaoyang District, Changchun, Jilin 130061, China, then move to Museum of the Imperial Palace of Manchukuo at No. 3 Guangfu Road, Kuancheng District, Changchun, Jilin, China.
That gives Changchun a route you can actually explain without falling back on generic district talk.
If you still want one extra stop, use Shang Palace at Shangri-La Changchun or Eurasia Shopping Mall only if it stays on the same side of town.
