Tips:

1, when the number of minutes is greater than 30, use "minutes++to++minutes", where "minutes" is 60 minus the original minute and "minutes" is "next minute", indicating "how many minutes are left".

2. When the number of minutes is less than 30, "minutes+past+minutes" means "what time is it".
