Meet Li Ching Yuen, the Chinese man who lived till the time he was 256 years old. Li Ching-Yuen or Li Ching-Yun (simplified Chinese: 李清云; traditional Chinese: 李清雲; pinyin: Lǐ Qīngyún) (died 6 May 1933) was a Chinese herbalist, martial artist and tactical advisor, known for his supposed extreme longevity. Whether true or false, there is definitely truth in the fact that the old Chinese man had lived an extremely long life. Having spent most of his time living in the mountains, breathing fresh non-polluted air, attaining a good knowledge of plant herbology and eating healthy, you can’t really doubt the fact that he was speaking the truth.

Li began his career as an herbalist at just ten years old, and for almost forty years, had a diet of mostly herbs, goji berries, lingzi, wild ginseng, he shoo wu, gotu kola, and rice wine. He continued this for the next 100 years of his life

For almost 40 years, he survived on a diet of herbs such as lingzhi, goji berry, wild ginseng, he shoo wu and gotu kola and rice wine. In 1749, at the age of 71, he joined the Chinese armies as teacher of martial arts. Li was said to be a much-loved figure in his community, marrying 23 times and fathering over 200 children.

According to one of his descendants, there was even another elderly man who lived as long as 500 years, and who Lee learned about the techniques of Qi Qung used in Chinese medicine and coordinate various patterns of breathing with various physical views and movements of body.

As one of his disciples stated, Li once meet an older person, who was 500 years old, and who also taught him about the exercises called Qigong, and gave him some dietary suggestions which are going to be helpful for him, to expand the lifespan to phenomenal proportions. Despite those exercises and a diet rich of herbs, what essential knowledge can we get from the Master of Longevity?
