The inflatable device is originated from the Chinese Red Double Happiness. This symbol is widely used in Asia during weddings. The whole piece is covered with soapy water and is self-sustained by a continuous pumping system.

Nowadays China's declining marriage rate has become a very serious problem. Economic pressures such as high house prices, high bride price, and high childcare costs have caused young people to be reluctant to get married. Urbanization, fast-paced life, work pressure and other factors have led to a decrease in the willingness of young people to get married. Social vitality has declined and the function of the family has weakened.
