Shanghai is a city with an eye to the future - but some residents are nostalgic for times past. Wu Ni chats to a 'retro-holic' who is collecting pieces of the lost city.

For many Shanghai natives, nostalgia is a natural reaction to the rapid and drastic changes that are happening to the city. Wang Xiaojia went a step further - she built a museum to commemorate the golden days of old Shanghai.

The museum is hidden away in the middle of a residential compound for war veterans. Stepping inside, one is immediately transported into the past, with a nostalgic atmosphere created by the dusky lighting, slow jazz melody and thousands of items reminiscent of old Shanghai.
