At the end of the TV series "Prime Minister Liu Luoguo", why was Liu Yong executed by the emperor? No, but it feels strange. Please explain it to me.

Gan Long didn't want Liu Yong to die. "Give Liu Yong a sword and commit suicide" is just a test for Liu Yong. Gan Long just wanted to see how Liu Yong would respond to such an order.

Liuyong went back to the office to commit suicide. He did find that there was no blade in the scabbard, and he realized that the emperor didn't want him to die.

Ending:

On the third day of the first month of Jiaqing four years, Qianlong died. Jiaqing arrested Xiao Shenyang on the day of Emperor Tai's funeral. Liu Yong kept delivering dining tables and talked with Xiao Shenyang in prison.

Under the last imperial edict, Xiao Shenyang hanged himself.

Liu Yong will eventually return to his hometown to support the elderly.
