Once Upon a Try: The art of discovery and invention

Many stories regarding three of ancient China's "four great inventions" - namely the compass, gunpowder and papermaking - are featured in an online exhibition launched by Google Arts & Culture on March 6.

Eight Chinese cultural institutions, including the Palace Museum and the Art Museum of the Central Academy of Fine Arts in Beijing, are taking part in the digital exhibition.

A documentary about contemporary artist Cai Guoqiang - who is known for creating art using gunpowder - and works by him also form part of the exhibition.
