Excuse me, where is the origin of Shi Yuhua? Liuhe or Yizheng?

I am from Nanjing, and I know that there are many raindrops in Liuhe and Yizheng.

Definitely not in Yuhuatai. It used to be a production (a long time ago), and now it is a martyrs cemetery.

In recent years, Yuhuatai has built a park for tourists to pick up the rain flower stones, which were shipped from Liuhe.

The huge chrysanthemum-shaped rain flower stone in Xuanwu Lake Chrysanthemum Exhibition is Liuhe, which is naturally uncut!

Rain flower stones are similar to agate in material composition, and usually gush out from the ground during volcanic eruption. What kind of silicon dioxide, iron oxide, copper oxide (so red) ... After a long time of reaction under underground high pressure, with the magma ejected from the ground, it was wrapped in volcanic rocks and turned into rain flower stone or agate. When the pressure reaches a certain level, it becomes agate with less impurities. If the pressure is too small, it can only be ordinary stones. Therefore, where there are volcanoes, there are more rainstones or agates.

Rain flower stones are formed by nature, and they sell 2 yuan in Yuhuatai. Isn't it a pity? After all, people are almost agate!
