IT is often said that Chinese are descendants of the dragon, but, according to a legend from the Shang dynasty, we are children of the bird.
Folklore has it that a woman who ate a bird egg gave birth to the first ruler of the Shang dynasty (1600 BC to 1028 BC), and for years many Chinese worshipped the bird as their god.
Jade artefacts from the neolithic age, before 1500 BC, reinforce the legend, as many relics, particularly those used in religious ceremonies and for jewellery, are in the shape of birds.
There are countless bird-shaped pieces on show among the 30,000 priceless jade artefacts being displayed by the Beijing Palace Museum for the first time to mark the museum's 70th anniversary.
According to The Complete Collection Of Treasures Of The Palace Museum - Jadeware I, which was published this month to coincide with the celebrations, most of the artefacts come from the palace's own collection and are deemed national treasures.
Jade collector Yip Wai-tat says much has been written about the bird-shaped jades because they're some of the earliest finds in China, but archaeologists have failed to agree on the origins and uses of many of the items on display.
