What is the relationship between China perpetual calendar and micro carp perpetual calendar?

It's okay. Micro carp calendar is a renamed version of China calendar. Renaming "Chinese Calendar" as "Micro Carp Calendar" is a comprehensive upgrade of the brand. The word "micro carp" is taken from the beautiful meaning of "carp becomes fish"; The icon "China Red" continues the classic elements and adds the tree-root ring design, bearing the long-standing traditional culture of China.
