In the Kangxi Dynasty, the xingsen and Shang persuaded Shunzhi to enter the empty door. What is the intention and purpose?

Xingsen and Shang persuaded Shunzhi to enter the empty door with three intentions
I. The Emperor Shunzhi experienced extreme grief after his death, and wanted to be short-sighted several times. Xing Sen and Shang and shun zhi had a very thick private affair and did not want to see shun zhi's martyrdom. the ancients said that the Buddha was able to calm down, so he actively persuaded shun zhi to leave his house.
2. xingsen and the Buddhist religion were still present at that time, having a mediocre position and had no questions. So he wants to make a big event, so it's amazing. The death of his wife happened to succeed, and Wannian was gray. Is there anything more advanced than making the emperor go home.
3. Buddha said that people are equal and everyone can join Buddhism. But since ancient times, who have seen the Emperor as a monk. Therefore, it is suggested that the good governance can show that the Dharma is omnipotent.
