Who is Yonghe in the online version of Biography of Mao Lie (the second season)?

Yonghe is actually a virus, which can also be said to be Li Wei's mother. The virus is in He Mei's hands, and the peach blossoms bloom and the phoenix trees fall. Some analysts say it's a person named Qin Ru, and Li Wei's mother used to be surnamed Qin. As has been said in the plot, if you find Qin Ru, you can find people who say the first two sentences of Yonghe's poems, and the last two sentences mean that Yonghe wants to live a long life, but he wants a million dollars. These two sentences are about life, and the drama repeatedly mentions a virus, which is the real harmony (this is only my own understanding). I suspect that He Mei already knows the prescription for this virus. This suspicion is not groundless. This is because someone laid out a big picture, and the things in the box may be related to the person who laid it out.
