Author: Thrift can cultivate one's health, tranquility can give birth to enlightenment [original] Thrift can cultivate one's health, feel the bamboo fence in the thatched cottage and indulge oneself; Quiet can give birth to enlightenment, that is, birds crow and flowers fall, which is a turning point. Happiness in life is bliss, and ten thousand hardships make a great man. A simple life can cultivate a person's health quality, so even living in a bamboo house will be interesting; A peaceful and calm environment can make people understand the true meaning of life, that is, birds singing and flowers blooming and flowers falling, and can also make people understand the vitality of heaven and earth. A relaxed and happy life is just an ordinary blessing. Only through suffering can we cultivate great men with outstanding achievements. [Comment] Well-dressed food is always less leisurely and more natural than life in a thatched cottage. In a quiet environment, it is easy to understand the truth between heaven and earth. My heart is like a mirror lake, and I can see the sky and clouds. It can really be described as "indifferent to ambition, quiet and even far away." True happiness belongs to those who suffer hardships. People who are carefree all their lives enjoy only mediocre happiness. A great man's life is mostly tempered, which is unbearable for ordinary people.
