Leaving the microscopic world behind, they strolled around nearby for a while, then headed to Michel Church, which offers a panoramic view of Hamburg City.
The church's architecture is Baroque and it's a landmark of Hamburg; ships entering the Elbe River see the church first.
The church is free to enter and they chanced upon an orchestra rehearsal, sitting down to listen for a while.
Reaching the top of the tower requires a ticket, 5 euros, for the 132-meter-high observation platform.
"Below this church lies Bach's tomb," Su Qing said on the elevator.
"When Mrs. Jing dies and gets buried in Chunshan, Chunshan will also become a popular attraction," Gege said.
Gu Ran grabbed Gege by the neck.
"What are you doing, assaulting me?" Gege said.
Xie Xiya raised her camera.
"Uh, uh!" Gege immediately put up a dying struggle, even grabbing Gu Ran's hand to lift her feet off the ground, pretending she was being choked into the air.
