Almost 200 international motoring enthusiasts have gathered in their vintage cars for the fifth Peking to Paris rally, a 12,000 kilometre driving adventure.
It was first run more than a 100 years ago, long before the Chinese capital was known as Beijing.
They have 33 days to complete the route, driving through some of the most remote areas on Earth.
