It's really a living example. I was once on the verge of liquidation. If @protocol_fx had been available at that time, I wouldn't have suffered such heavy losses. Sometimes when your position is on the verge of limit, the market has actually reached its limit. You just need to hold on for a while longer to get through it, but human nature is unreliable. Using appropriate Defi protocols to solve the problem of hard liquidation is the only correct choice.
