In his spare time he likes to visit Yuyuan Garden and eat with the locals along Sipailou Road, a famous old street in Shanghai which is soon to be demolished.

"I like the shuijiao there," he said, referring to the dumplings served at tables along the street outside eateries.

"That's the Shanghai I like," he said.

He usually stays out late if he doesn't have to work the next day.

"Please tell them not to tear down Sipailou," he said.

Jana Kruger, 24 years old, might be the youngest manager of a pavilion but she is an experienced exhibition organizer.

In 2008 she worked for the water-themed Expo in Zaragoza, Spain, so she already had Expo experience.

Her six-month Shanghai visit is her longest stay in Asia.

"It's amazing to see that so many visitors can be organized so well," Kruger said of guests at the Hamburg "passive energy house."

The house, one of the most costly in UBPA, is energy neutral and will remain as a reference for future projects.

It is solid, compact, air-tight, well-insulated and uses solar power.

It reduces energy consumption for heating in winter and cooling in summer.

Thanks to the design of the Hamburg House, Kruger said she doesn't need to bring a lot of clothes for changes in the weather. The temperature in the house remains at around 25 degrees Celsius around the year.
