Who are the emperors in history who are over eighty years old?

In fact, there have been more than four hundred emperors in the history of our country, all dynasties, but there are not many emperors over eighty years old, and there are four emperors I know of who are over eighty years old, the first of which is the Liangwu Emperor we are familiar with, which is what we call the Nianfo Emperor, who was the first emperor over eighty years old, but unfortunately he was desolate in his old age and was finally starved to death. I only know that I am over eighty years old, but I don't know exactly eighty. Then, the second emperor who was more than eighty years old was the only orthodox female emperor in history, Wu Zetian, whose original name was Wu Meiniang, also known as Wu Cao, entered the palace at the age of fourteen and became a talented person of Li Shimin, officially ascended the throne at the age of sixty-seven, ruled for more than twenty years, and then abdicated because of the Shenlong coup and died half a year later. Let's talk about the third emperor who is more than eighty years old, he is the first emperor of the Southern Song Dynasty, Emperor Gaozong of Song, who is also an emperor over eighty years old, and later abdicated as emperor Taishang. The fourth emperor over the age of eighty was the Qianlong Emperor of the Qing Dynasty, who had been emperor for sixty years and the Taishang Emperor for nearly four years, who lived to be eighty-nine years old, the longest-lived emperor in history, and the longest-reigning emperor in history. (Although his grandfather Kangxi reigned for sixty-one years, Kangxi did not really hold power for six years, and for six years he was an auxiliary minister.) These are the four emperors in history who are more than eighty years old, and of course, Kublai Khan, the ancestor of the Yuan Dynasty, was almost rated as seventy-nine years old, only a little bit.
