According to historical records, an aunt of Zhang has been committing adultery with one of Zhang's guards for a long time. Because these two people are top secret, they have never been discovered by Zhang. In the end, it was completely accidental. Here's the thing: Zhang never signs a check without a stamp, but just pokes it with a red brush and dots a red dot on it. However, no matter how big the check he writes, the bank will pay it correctly. The matter was learned by the above-mentioned guards. The guard officer felt that there was an opportunity, so he used his crooked brain to cheat. He had long wanted to fly away with Zhang's aunt, but they couldn't do it because they didn't have much money on hand. One day, the guard officer conspired with Zhang's aunt to fill in a huge sum of money on a blank check. Then, according to Zhang's practice, he poked the red dot on the check with a red brush and went to the bank to withdraw money. After preparing to get the money, the two fled together. Who knows, just as they were waiting to withdraw money from the bank, a group of gendarmes suddenly rushed in and arrested them. So, what's the difference between a check issued by a guard officer and a check issued by a guard officer? It turns out that Zhang's brush is not an ordinary brush, but a special brush. In this special brush, a steel needle is hidden. Every time Zhang Zuo Lin writes a check, he has to poke a hole in it with this special brush, otherwise the check will be invalid. The bank recognized a new check with only a hole and no red dot. The guards and concubines only know one thing and don't know the other. They think that this check is just a dead letter. Therefore, their forged fake checks were quickly exposed and their adultery was exposed. But Zhang remembered that the bodyguard officer had followed him for many years, not only did he not kill him, but also gave him his concubine and gave him a sum of money to let them fly away and live their own lives.
