Li Ching Yun had an advice for living a long life: "Keep a quiet heart, sit like a tortoise, walk sprightly like a pigeon and sleep like a dog" - and apparently, he followed his own advice, because Li died at a ripe old age of 256!
Environmental Graffiti has the story:
By his own admission he was born in 1736 and had lived 197 years. However, in 1930 a professor and dean at Minkuo University by the name of Wu Chung-chien, found records “proving” that Li was born in 1677. Records allegedly showed that the Imperial Chinese Government congratulated him on his 150th and 200th Birthdays.
