These bonds were picked up by Louis Koo after shooting the robbers at the scene and put in the glass trough of his car door. Louis Koo was actually cooperating with the robbers, but at first he was responsible for selling bonds for cash, but later out of curiosity and worry, he ran to the scene. Seeing his fellow fat man killed, he wanted to stop the robbers from killing, so he all KO. Who told them not to listen?

Later, he saw that the trading period of his account was coming, but he was short of funds, so he opened the account of his immediate female boss, Li Bingbing, and moved her money to his account to delay the time and replenish the funds. The rest of the time is trading time.

Later, he called again because it was time to trade, but his account still didn't have enough funds, and he still didn't make any money from the foreign exchange he bought. In order not to let others find out that his account was in debt, he had to use Li Bingbing's account to transfer money to his account again. I hope I can wait until I exchange the robbed bonds for money before covering my positions.

It was also because he embezzled public funds and had financial loopholes in his account that he thought of planning to rob those bearer securities with his friends to make huge profits.
