In 2010, to celebrate Shanghai World Expo, the artist Huaibing Guan has conceived a public artwork, called "Travel in Time". This is a maze like structure with paths inside. The interaction between viewer and the artworks is pleasant. People can go through the paths to experience of traveling in time.
It's a boat like maze and the works are made up of around 30 separate pieces. The components of this works are square stainless tubes.  This works measures 88 feet long (26.40 m) and 13 feet wide (3.90 m). It's fabricated with stainless steel by hand.
A such stainless steel fabrication is a laborious works which requires the metal worker with rich experience and knowledge.
