What does the poem "Praise the Army God" mean?

Guan Yu was poisoned by an arrow in his upper arm and there were no bones left. He had to scrape off the bones to detoxify.

Former bone curetter-Guan Yu and bone curettage.

Look at the romance of the Three Kingdoms.

Hua tuo curetted the bone and healed Guan Yu. Guan Yu insisted on having sex with others while scraping bones without anesthesia. His face hasn't changed, and his chess style is not chaotic!
