There is a place in the mountainous area of southern Zhejiang. The mountains are continuous and not very high, but they are not as gentle as the hills in the plains. What's more, the mountains are closely connected. There are very few plains between the two mountains, and most of them are occupied by a stream. Therefore, since ancient times, there have been nine mountains, half water and half fields, eight mountains, one water and one water and two fields, etc. Although they are different, they all mean that there are many mountains, few water and few lands and few lands. In such a poor place, the connection with the outside world is not only the bamboo on the stream, but also the direction of the stream has been opened up one mountain road after thousands of years.
