Our exploration of China begins in the warm,
subtropical south.
On the Li River,
fishermen and birds perch on bamboo rafts,
a partnership that goes back more than a thousand years.
This scenery is known throughout the world,
a recurring motif in Chinese paintings.
And a major tourist attraction.
The south of China is a vast area,
eight times larger than the UK.
It's a landscape of hills but also of water.
