Zhang San and his uncle made a scheme in high-seas fishing U merchants, making a profit of 2 million in one deal, and afterwards they could be sentenced to life imprisonment with a 50-50 split.

Zhang San said he cooperated with his uncle, specifically targeting U merchants with funds, to set a trap for them. The whole case process involved Zhang San connecting with a financial platform, claiming he wanted to invest, and the financial platform told Zhang San that to invest, he would need to use U. Zhang San stated that he didn't have U, and the financial platform said they knew a U merchant who could arrange cash transactions for Usdt.

Then the financial platform found a U merchant to come to Zhang San for cash transactions. The U merchant gave Zhang San U, and Zhang San gave the U merchant cash. After Zhang San handed over the cash, the U did not transfer to the financial platform but instead reported to his uncle, claiming that his U and money had been defrauded. Then he sought help from his cooperating uncle, and a few days later, the cooperating uncle had the U merchant detained, seizing the 2 million cash delivered due to the U merchant's suspected concealment crime, and afterwards Zhang San split the profits 50-50.

If this case is real, the actions of Zhang San and his uncle constitute fraud, and the amount of fraud exceeding 500,000 could lead to over 10 years imprisonment, with a maximum sentence of life imprisonment. Some say that the way Zhang San and his uncle cooperated is actually a form of robbery in disguise, and not only that, Zhang San's actions could also constitute the crime of favoritism and abuse of power, falsely charging the innocent U merchant with a concealment crime. Zhang San is considered an accomplice, and multiple crimes would be punished cumulatively, with a maximum sentence of life imprisonment.
