I have learned that there are many incorruptible poems and calligraphy works, such as "honest and clean", "diligent and incorruptible", "honest people always enjoy themselves", "frugality is the foundation of incorruptibility" and "self-cultivation". These calligraphy works not only show the values of honesty, but also give people visual enjoyment and spiritual enlightenment with beautiful fonts and smooth lines. These works have profound implications, and educating people to maintain the qualities of honesty, diligence for the people, happy life, thrift and honesty is an important content of building a clean and honest culture.
