letian

In a small peaceful town along the coast, called "tunny town" , lives our leading role, Qi Letian, an ardent boy with red hair.

宁静的海边小镇“金枪鱼镇”里，有一个红发少年齐乐天。

We visit Letian pottery workshop. In Letian we saw many artists from all over the world, doing their work seriously. I admire them.

去了乐天陶社参观了一下，看到了很多来自世界各地的艺术家认真工作的状态，真让我佩服不已。
