Song Meiling in Taiwan Province was not written by herself, but by the secretary and the nursing staff. The following excerpt is related to colons.

Song Meiling insists on enema every day, injects clean water into the body before going to bed every day, cleans the dirt on the intestinal wall, and keeps the lower part of the intestine clean before bathing and sleeping, such as rectum, S-shaped colon and descending colon.

(PS: This is mainly because her family believes in Mormonism. In Mormon mythology, there is a story of an old woman who washed her stomach according to God's instructions and rejuvenated. Butter and water enema are popular among some believers to prevent diseases. )

And weigh yourself before going to bed every day. Once you find that you have gained a little weight, you will modify the recipe the next day.

This is also an important reason why she can live to 106.

I hope my answer will help.
