Master Kong Hai of Lingyin Temple. In Chang'an in the ninth century, Japanese ambassadors to the Tang Dynasty came along. Kunghai monks first studied at Ximing Temple in Chang'an, then entered Qinglong Temple in southeastern Chang'an to seek Buddhism from Huiguo monk. After returning to China, Kunghai monk founded Zhenyan Sect, and together with Tiantai Sect, which was founded by another most clear monk in Tang Dynasty, brought Japan into the era of secret religion. However, with the demise of the Tang Dynasty, the Secret Religion disappeared in China. Because the esoteric religion worships the Great Sun Tathagata, the name of Japan is interpreted as "the Great Sun's Nation". The great God of heaven shines in the same body as the great sun Tathagata. After reading the bronze statue, I have two feelings. "First, the bronze statue is a memorial to the twentieth anniversary of the friendship between China and Japan. Putting the relationship between countries into the long history, it seems that the weather is uncertain and the warmth and cold are not the norm. The voice of the nation's shame is still pouring into our ears. The second is about Metallurgical technology. Seeing the introduction behind the bronze statue, this bronze statue adopts the high-tech technology of a Metallurgical Research Institute in China, which makes the copper rust-free and colourless. It is true that this bronze statue has indeed experienced the baptism of time. But I remember that the Xuande stove was made of wind-milled copper for Siam tribute. Wind-milled copper is named for objects made of this kind of copper, which will not rust. The brighter the wind blows, the brighter it will be. To my layman, this stainless technology already exists. Modern technology must be more advanced, but the explanation behind this bronze statue does not seem to convince me where is better than the wind-milled copper technology of Siam in the Ming Dynasty.
