How to escape when you meet a tiger in the forest?

There is a joke about what people should do when they meet tigers in the wild. Hold your head high, open your eyes, open your arms, yell at the tiger, and finally die with more dignity. This joke has always been regarded as a joke by many people, but I once saw a documentary in which a zoologist told his experience of running away from a tiger. Because the method he used was very similar to that in the joke, I was deeply impressed, but I can't remember the name of the zoologist. Tiger is a territorial animal, and sometimes it attacks you just because you broke into its territory. Some experts have said that if you find the tiger staring at you motionless, it means that you have entered the warning range of the tiger. At this time, never run away and bend over. You can only face it quietly and step back a little. If the tiger has started to attack you, hold your head to protect your throat and shout loudly, hoping someone can save you.
