Which episode is the son of the four treasures of the command being beaten by Kangxi?

1, "Four Treasures of the Command" is about the time when Emperor Kangxi made a bet with a monk. A few years later, a stutterer among beggars became an eloquent jester, and another emaciated man became a national famous general. Later, Nalan and Shi both occupied the best official positions, and were in power in one's hand and one's hand, becoming the imperial Four Treasures of the Study before Kangxi. Although the four became brothers, they had different personalities and many contradictions. Sometimes they help each other, sometimes they destroy each other. However, when competing with the "three treacherous officials", they were able to share the same enemy and plead for the people. Singing and dancing in triumph, I found that wherever I went, corrupt officials set up many mysteries, and local tyrants harassed him with complaints. Every time the four treasures of the Imperial Command go with the driver, they show their abilities, or they are observant, brave and good at fighting, or they laugh and curse, or they pretend to be crazy and sell stupidity, killing traitors all the way to get rid of tyrants and pleading for the people, and often they can make great achievements.
