The relevant laws are not perfect: Guan Jinsheng was the bane of the "327 National Debt Incident", but he was convicted of accepting bribes. 1999 before the amendment of the new criminal law was issued, there were no related crimes in the old and new criminal laws.

The futures related system is not perfect: 8 minutes before the closing of 327, the situation suddenly changed! On the huge electronic display screen, an empty bill with a total amount of several hundred billion yuan fell from the sky, and "327" was smashed from 152 yuan to 147.50 yuan. Guan Jinsheng took advantage of the loopholes in the margin system in the early futures market to expand funds indefinitely.

Imperfect supervision system: Guan Jinsheng's manipulation of treasury bonds futures has not been effectively monitored in real time. On the contrary, after the closing, it took the Arbitration Commission six hours to announce to the whole country through CCTV that the transactions after 23rd 16: 22 and 13 seconds were invalid, and 15 1.30 yuan was the closing price of the day.
