Two true and two false gems. Some people have received a real gem. What was their fate? Some people have received a fake gemstone. What was their fate? This is a plot line. Let's look at it the other way around. Those who previously got fake gems now get a real gem. What is their fate? Those who previously received a real gem now receive a fake gem. What is their fate? This is the second plot line. And what is the fate of these people who have all obtained a real gem? This is the third plot line. Or maybe these people all got a fake gemstone, so what is their fate? This is the fourth plot line.
Intention: There are many factors that determine a person's destiny, and they cannot be generalized.
