Well, the "327" event in 1995 is indeed interesting.
That incident is quite long ago. So I had not experienced of it.
My thought is that both long and short of that bond futures in year 1995 involved some insider trading. And traders of both sides got over-confident.
And which site caused bigger trouble, in this incident, it was the short sellers, got more severe legal punishment. It's measured by damage and risk they brought to the exchange. Many of them had traded far beyond their margins.
So it's not about which side was helping the government fixing inflation, but mostly about traders betting much more money than they actually can pay. And it's also about the exchange didn't have right risk control by then.
There're many things been fixed since this event. And as always, the top rogue trader went to jail.

Yes I already quoted that website in my previous comment:
Why did they put somebody who was helping the government with his trading activities in jail especially when his trading activities was helping the government to achieve what they wanted to achieve faster? I don't get it. https://ebrary.net/11532/economics/treasury_bond_incident
Second, why nullify the transactions of the short side only?? This puzzles me even more. If you are saying both sides were engaged in insider trading and were trading in bigger sizes than what they should be, then the fair thing to do is to nullify transactions of BOTH sides, both the long and short side. The long side, from what I read from the article from ebrary.net actually engaged in heavier trading than the short side and started earlier during that day and one ally company of Wanguo securities that was supposed to go short switched side and went long instead so that shows that obviously "insider trading" like what you stated from the long side was just as bad and maybe even worse than the short side and yet none of the long transactions got nullified and none of the security companies that went long in their transactions got punished let alone going to jail??
And thirdly, the exchanges nullified the transactions at PRECISELY where the price was pushed to the highest level of the day and since all of the exchanges in China are owned by the Chinese government, it's clear that the government preferred that the government bond futures' prices go up and not down even though from an economic point of view, the prices of the government bond futures going down would help the government with its inflation-fighting objective. That's why I was really confused why the government would choose to punish the company that shorted the government bond futures when his transactions made more sense from an economic point of view. And I was even more confused that not only the government caused the security company to suffer substantial trading losses but also threw the CEO in jai!!
