I had a good time in sanya

I had a great time in Sanya. If writing a composition, you can expand it like this: I had a great time in Sanya. Sanya, a beautiful coastal city in Hainan, is really a paradise on earth. The moment I arrived in Sanya, I was attracted by its beautiful scenery. The sea there was so blue that it seemed to merge with the sky at the horizon. The soft sandy beach was like a huge golden carpet. When I walked on it, the sand slipped through my toes, which made me feel extremely comfortable. The local people were very friendly. They were always ready to offer help when I needed it. I also tasted a variety of delicious local fruits, such as coconuts, mangoes and pineapples. Their sweet taste still lingers on my tongue. In addition, I participated in some interesting water sports, like surfing and diving. Surfing on the waves made me feel full of vitality, and diving allowed me to explore the mysterious underwater world. There were colorful corals and all kinds of beautiful fish. All in all, every day in Sanya was filled with joy and surprises, and I will always cherish this wonderful memory. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The realm of the netherworld

The netherworld realm was the netherworld of the earth, and it had different manifestations in different cultures and story settings. In the settings related to the Journey to the West, the underworld was called the "Netherworld Realm." It was a place that governed the life and death cycle of ten species in the Three Realms. There were ten Yama Kings and Ksitigarbha Bodhisattva in charge of guarding it.(Before and after the Antian Meeting, they belonged to the Heavenly Court and Buddha, but they were all subjects of the Jade Emperor.) There were many special books here, such as the General Book of the Kings of the World, the Book of Life and Death, etc. In some stories, the netherworld, as the Yin law of the Heavenly Dao, had the characteristic of being indestructible. When there was a problem with the Yang nature of the Heavenly Dao, it would take advantage of it. There were also some mysterious and gloomy places that were compared to the underworld. For example, the abandoned villas at the foot of Jinyun Mountain in Beibei, Chongqing, looked as gloomy and terrifying as the huge underworld. The novel "Underworld Commander-in-Chief's Bloody World" is equally exciting. Everyone is welcome to click and read it!
