Who was the first person who wanted to rob the birth class?

In the story of "The Story of the Birth of an Intelligent Robber", Liu Tang, the red-haired ghost, was the first person to contact. However, when Liu Tang and Classical put forward the idea of seizing the birth outline, they said this:

"I found out that Liang Zhongshu, a famous government in Beijing, bought 1, gold beads, treasures, toys and other things and sent them to Tokyo to celebrate the birthday with his father-in-law, Mr. Cai. Last year, I also sent a hundred thousand gold balls to the baby. On the way, I don't know who robbed me, but I haven't caught it yet. This year, I bought another 1, Kim Jong-il babies, and arranged to leave sooner or later, in order to catch up with this June 15th birthday. I think this set is ill-gotten gains, so why not take it? "

This passage is clear. In the year before this, there was an incident in which the birthday class was robbed, but the suspect was not found. It can be seen that the seven people who wanted to rob the birth class and succeeded in robbing the birth class in Water Margin were not Chao Gai, Wu Yong, Gongsun Sheng, Liu Tang, Bai Sheng and three brothers Nguyen.
