As happy as Zhang Jiale, as happy as Su Muqiu. What do you mean?

Zhang Jia Le and Su Muqiu are both characters in the novel Full-time Master.

Zhang Jiale

Professional players, runner-up four times in ten years, missed the championship, many ranked second and never got the first place. Orz's occupation of manipulating the character [Hyun Hua] is an ammunition expert [a profession that uses both grenades and automatic pistols], similar to the rifleman in the island's very popular animation Destiny Zero. But the rifleman in this animation is always unlucky and full of ups and downs, so some people call it "rifleman since ancient times."

Su Muqiu

He almost became a professional player of Harvest Team, but only one step away, because he died in a car accident on the day he signed with Harvest Team at the age of 17 and was buried in Nanshan Cemetery in Hangzhou. He was a dead man at the beginning of the story of the full-time master.

So this sentence means that luck is as good as that of Zhang Jiale, that is, luck is extremely bad, and life expectancy is as long as that of Su Muqiu, that is, life expectancy is very short.

Hope to adopt!
