Dragon Boat Holiday walks: Join Historic Shanghai on this  walk through the lanes of Hongkou, inspired by the book "Shanghai Homes: Palimpsests of Private Lives", in which author Jie Li explored the layers of history and dimensions of private lives in her grandparents’ lanes. Those lanes are gone now, but you'll enter similar century-old lilongs—now threatened—and delve into their history and their stories as the life cycles of these lilongs reach their end.
