What does it mean to show success on the second day of IPO subscription?

The distribution quantity of subscribed new shares shall be uniformly distributed to investors by the registration and settlement center of listed companies after the subscription and capital verification are completed according to the prescribed procedures. After being matched, the listed company will decide whether it can win the lottery by drawing lots. If you purchase new shares on T day, you can check whether there is a matching number on T+ 1 day. If there is a matching number, the subscription operation of new shares is successful. Check the winning results on T+2. If there is a lottery, ensure that the fund account has enough funds for the subscription of new shares at the end of T+2.
