Like fortune tellers and palm readers, what is true or false, and how do they work it out? Is there any scientific basis?

I read palms. I read more than 1000 palms. When the accuracy is above 85%, it can reach 100%. According to the lines of the main line in my hand and the tiny lines on it, we can see what happened in those years, such as the progress of marriage, first love, marriage and divorce, career and employment changes, and some comparative things, such as demotion, salary reduction and salary increase. We can see more than 300 diseases on our hands.
