For a person who has never seen a volcano with his own eyes but is full of curiosity, the crater park in Haikou is definitely a must-see attraction when he comes to Hainan.

driving from Haikou, we soon arrived at the gate of the park. When you get off the bus, you will find that almost all the stones are black as far as you can see. This has never been seen in Hunan. It turns out that these black stones are volcanic rocks. Pick up a piece and have a look. It is slightly lighter than ordinary stones, and the stones are full of holes.

when you enter the scenic spot, the words "National Geopark" are engraved on the big stone at the entrance. There are several popular science museums of volcanoes in the park, all of which are descriptions of volcano knowledge, including text descriptions and video explanations. There are both domestic and foreign volcano introductions and some physical exhibitions related to volcanoes, which are very knowledgeable and I like them very much.

the park is a volcano. So many remains of volcanic eruption at that time remained. There are several signs like "lava flow" on the roadside. In the direction of the signs, you can see the scene that lava flows out of the volcano and solidifies in an instant. One strand, like several huge ropes, is twisted together. When you look closer, there are also many round holes in the rock, just like what you see at the door.

there are volcanic dwellings at the foot of the mountain. It is said that ancestors lived near the volcano during the Qin and Han Dynasties. The ancestors used local materials and dug volcanic rocks to build houses. They don't need lime or mud, so they just dry up. I searched on the Internet. Volcanic rocks are high-quality building materials. They are warm in winter and cool in summer, and have good air permeability. Our ancestors are really smart. Such houses can also be seen in Sanqing Village and Meishe Village, ancient volcanic villages in Hainan.

Some farm tools and furniture are also displayed in the houses. Furniture can be divided into two types according to material: wood and stone. The farm tools look strange. Guess what they are for.

this is used for squeezing sugarcane juice and oil. In my opinion, it is a little rough, such as hollowing out a piece of wood without any decoration and beauty. It feels quite primitive, maybe it is also a kind of simple beauty. Stone is mainly some instruments for beating and ramming. The surface of the furniture is very smooth, and a cabinet lying horizontally on the ground can also be used as a bed. It's a little too narrow. Furniture production is slightly more exquisite than farm tools, but there are no carvings, paintings or colors, and it is also very simple.

Looking around the houses and appliances, I seem to have traveled through time and space: slash and burn, work at sunrise and rest at sunset. Stone chips splashed and tinkled, which was dug in volcanic rocks by our ancestors; In the harvest season of sugarcane, cut down bundles of sugarcane and squeeze out sweet juice; The sound of knives and axes, the song hey hey, the tree fell to the ground, whose family is going to marry a daughter, cut down trees for furniture dowry ... Maybe this life is primitive and hard, or maybe it has her simplicity and simplicity, who knows.

I walked out of the houses and started climbing mountains. The mountain was not very high, and soon it climbed to the top. The stone tablet on the top of the mountain says "Haikou commanding height is 222.8 meters". This commanding height, well, is really not high. It is said that you can see the sea when it is sunny. It's foggy that day, so you should see the sea. Standing on the top of the mountain and looking around, although the vegetation is very lush, you can still vaguely see the circular crater.

once you get to the top, it's time to get off. But this "down" is down to the volcano. The stone steps are steep, and even the most lively children are careful to hold the railing and walk slowly. After about 15 minutes of hard walking, we went down to the belly of the volcano. Looking up, people seem to be in a deep well with a cone shape, and suddenly they have the feeling of "sitting in the well and watching the sky". Look around the wall of the "well" again, the plants grow very luxuriantly, and some of them hang down long vines, just like green bead curtains.

There is also a stone tablet at the bottom of the cave: the place where lava erupts. One day about 8, years ago, the rocks in this cave mouth melted. The higher the temperature, the more molten the rocks became magma. They boiled, braved sticky black bubbles, and the bubbles burst. The magma splashed on the stone walls on both sides, and the water generally dripped down. The rock walls on both sides are constantly being melted and collapsed. Gradually, the lava pool is getting higher and higher. air billow is steaming, growling, and rising with thick black smoke, making frequent growls. Finally, he can no longer resist its mania, spewing out, and then falling down ...

Nature is really terrible and magical. Man always claims to conquer nature. In my opinion, man has never defeated nature except destroying it. Humans should be kind to nature and live in harmony with it.

I'm a little tired from climbing out the other way from the hole. Walking along the circular hole for half a circle, looking for the steps down the mountain, the time is about four o'clock in the afternoon. The sun shone on the stone wall, and suddenly my eyes were flashed by many shiny things. When I got closer, it turned out that the tiny water droplets hanging on the moss were lit up by the sun, reflecting colorful rainbows. It's beautiful, and there are eggs to send down the mountain!
