Who did the Tang king use as a victim to burn the gods when praying for rain?

As early as the Shang Dynasty, there were records of praying for rain, and Shang Tang even wanted to set himself on fire and pray for rain. At that time, the sun was shining, the rivers and wells dried up, the vegetation withered, nothing grew, and hunger was everywhere. At the beginning of the drought, the Shang Dynasty used manpower and material resources to fight drought, such as digging wells and ditching, and diverting water for irrigation. But the drought is getting worse and worse, and these means are useless. Shang divination learned that "it doesn't rain, it's heaven." So Tang ordered people to set up an altar in the suburbs, and sent people to make "suburban sacrifices" every day (burning firewood and offering sacrifices with cows, sheep, pigs and dogs. During the sacrifice, historians held a tripod full of sacrifices and prayed devoutly, but day after day, year after year, there was still no sign of rain. The drought lasted until the seventh year, and Tang Zhen couldn't sit still. He ordered the historian to set up an altar in the mulberry forest and personally led the minister to beg for rain and sacrifice, but it still didn't help. Tang also ordered the historian to divine and learned that burning firewood to worship heaven required "human sacrifice." The living are burned on firewood to move the spirits of heaven and earth. After listening to this, Tang said, "I prayed for rain to save people. How can I burn it with others? " Just use myself instead! "After that, I ordered people to set up a woodpile, let the left and right sides cut off their hair and nails, take a bath and clean themselves, and pray to God:" My sin alone cannot affect all people; If all countries are guilty, I will bear it alone. Don't harm the people because of my own immorality. "After the prayer, he resolutely sat on the woodpile and ordered people to light the fire. Just then, suddenly, dark clouds billowed, the wind blew hard, and a rainstorm suddenly came. It is a natural phenomenon that the long drought meets the rain. Businessmen, on the other hand, are stupid, thinking that this is because Tang dared to sacrifice himself and touched God, and then he sent down dew to help all people.
