credit cards have a credit card spending limit every month for more than three months in a row. Don't use it for a while and then freeze it for a long time, so swipe your card regardless of the amount. The more times you swipe it, the better.
natural month: it is a natural month from the first day of each month to the last day of each month, such as March 1st to March 31st. Non-natural month: it starts from any day in a month and ends on the same day in the next month, which is also a month, but it is not a natural month. For example, March 15th to April 15th is an non-natural month.
