Before long, Kangxi felt that it was too inconvenient to do so. 10 boxes contain different jewels. 10 courtiers can't always be around and stay in one place ... In short, can you think of a simple and easy way to open any box at any time, instead of wasting time and effort as it is now?
The civil servants and military commanders around Kangxi came up with ideas and tried to do this, turning and turning, but never came up with a perfect way.
On this day, the little eunuch Buzara stood aside and knelt on the ground and said, "Your Majesty, I have an idea."
Everyone was surprised when they saw it. It turns out that this Buzara is a little eunuch who just entered the palace, and he is still a child!
Kangxi looked at him and said, "You're welcome, just tell me."
Buzara stood up and said unhurriedly, "Isn't there two keys in a lock? The original 10 key is also in the charge of 10 modern minister respectively. Take out the sealing keys of 10, which correspond to the locks and boxes one by one, and number them from 1 to 10 respectively. Then put the key of 1 in box 2, the key of 2 in box 3, put it down in turn, and finally put the key of 10 in box 1. In this way, every courtier in charge of a key can open the box he is in charge of, or take out another key in the box, open the lock on the next box, open the next box, and then take out the key to open the next lock ... If this continues, you can open any box you want. In other words, as long as any recent minister holds the key in his charge, he can open 10 boxes step by step. Isn't this much more convenient than the way that a key can only open one lock? "
After listening to this, Emperor Kangxi and his ministers thought calmly for a while, and then nodded in praise, because it was really a simple and ingenious method.
