"As everyone can see, right after Chen Guangrui got married, he immediately received an appointment. It was not just any appointment, but one with a mandatory order to depart right away, without even the permission to bring any attendant. This is because Chen Guangrui cuckolded Emperor Taizu of Tang."
"After that, Emperor Taizu ordered Liu Hong to kill Chen Guangrui, and then went to Jiangzhou with Yin Wenjiao. You all can probably figure out what happened next. To prevent Tang Monk from discovering his true heritage when he grew up, Emperor Taizu ordered Liu Hong to silence him. Who would have thought that Yin Wenjiao, in an attempt to save her son, would actually put Tang Monk into the river and let him drift away, only to be eventually saved by a Bodhisattva in the guise of an old monk."
