Is the winning rate of China Resources Maotai related to the purchase amount?

The winning rate of China Resources Maotai is related to the purchase volume.

Because the subscription funds of new shares generally far exceed the funds planned by newly listed companies, it is necessary to randomly allocate shares among all subscription funds to ensure the fairness of subscription.

The Shanghai Stock Exchange stipulates that the subscription unit is 1 1,000 shares, and the subscription number of each account is not less than 1 1,000 shares, and the number exceeding 1 1,000 shares must be an integer multiple of 1 1,000 shares; The Shenzhen Stock Exchange stipulates that the subscription unit is 500 shares, and the subscription number of each account is not less than 500 shares. The number of shares exceeding 500 must be an integer multiple of 500 shares.

Each valid ordering unit corresponds to a matching number. The winning number (that is, the winning applicant) is determined by random allocation.

Then the ratio of winning units to the total number of effective units participating in the subscription is the winning rate of this subscription.
