Late at night, Liu Simin left the police station alone, writing to Cui Litian in the name of Cui Hai. Over the years, he has been pretending to be Cui Hai to send money to Cui Litian, and it is also he who makes Cui Litian think that his son is still doing well. In the hospital today, Liu Simin learned that the old man who was deceived was Cui Litian. He said in the letter that he was promoted and raised, and that he would send more money every month than before. This is the only thing Liu Simin can do for Cui Hai.
