I would like to ask whether I would need to renew my Chinese visa or not in order to stay > 90 days

As I would like to stay in China from the end of June till the beginning of October, 90 days (indicated as the amount of days at 'duration of each stay' on it) is too short for my stay. But since I have two entries, I am wondering whether the 90 days count per entry or for the two entries in total? At 'enter before' it states a date in November.
