Regarding the cycle of five virtues
In the cycle of five virtues game, initially Spleen represents earth, Qin dynasty represents water so Chen Ran jumps on that, now earth generates metal, and earth destroys water, so these two cannot be jumped on. Chen ran reasons that Qin is ok as it was the first dynasty to follow Zou Yan's doctrine. I don't seen how this is anything but a dangerous guess as it doesn't really matter if Qin came first if the danger is earth. But it turns out the danger was fire and it was reasoned wrong, isn't it pure luck they didn't get burnt?
