Mahoney's 12345 Interview Diary: Wall keeper vs path seeker

In Beijing, the subway is the fastest, most affordable, and eco-friendly way to travel. In this episode, Professor Mahoney visits Zhengxin Garden Community, located near Songjiazhuang Station, a key hub where three subway lines intersect.

Although Zhengxin Garden Community is close to Songjiazhuang Station, residents must walk nearly a kilometer to access it, because a wall between Zhengxin Garden Community and Hongshi Homeland Community block the former's access to the Station.

Residents of Zhengxin Garden Community propose opening a gate in the wall to ease travel, but residents of Hongshi Homeland Community disagree, citing concerns over losing limited parking space.
