Over 140 rare cultural relics from Sichuan's Sanxingdui and Jinsha, including two Bronze Age ruins from the ancient kingdom of Shu, were brought to Beijing's Poly Art Museum on Tuesday to give audiences a glimpse into ancient China's diversified culture, the Beijing Evening News has reported.

The exhibition is the first time that the cultural relics from Sanxingdui Museum and Jinsha Ruins Museum have been shown together.

The items on show include carved jade, gold, bronze, stone and ivory artifacts. These are brilliant examples of the flourishing culture of the ancient kingdom of Shu, a prehistoric civilization far away from the Yellow River which existed some 3,000 to 5,000 years ago.

Both ruins provide evidence to the theory that the Yellow River was not the sole starting point of Chinese civilization.

The exhibition will last until August 31.
