Amazing drone footage shows the vast scale of the salt fields in China- which look like an artist's paint palette.

The salt production in the Chinese province of Shandong has seen swathes of rural areas turned into colourful and everchanging tiles - yellow, green, orange and blue.

The northern coast of Changyi has a long history of salt production and is an important raw salt production area and salt chemical industry base.

The expansive salt fields are an example of economic development in the area but are also stunning to look at.
