Tu Zi Quan is a small community in China. The community of Tu Zi Quan very heavily centres around agriculture, specifically growing rice in paddy fields.

Once, the old water wheel at Tu Zi Quan broke, and Thomas had to deliver a new one - made of bamboo - to replace it.

The town of Tu Zi Quan is located alongside the Chang Jiang River, which was how the water wheel travelled to the rice fields after Thomas lost it.
