A thorough analysis of the natural factors such as location, surroundings and sunlight hours resulted in a fully open architecture for the Xi Tang. The concept of the Xi Tang lighting comes from the traditional Cantonese wedding custom of lighting lamps. On the day of the wedding, the wedding room is lit up in pairs with lamps, which means "long and bright". In the local culture, the lighting has a special meaning, as it symbolizes the elimination of filth, good fortune and a brighter state of mind. The light spreads along the shape of the corridor, creating a graceful curve of the building.
