Why is the historical low price negative

The historical lowest price of the rich road is calculated by using all the historical k-lines to do the pre-restoration operation and find the minimum value. Take Tencent as an example, Tencent opened at about 4 HKD on the first day and paid a cumulative dividend of more than 7 HKD today. When doing the pre-restoration operation, the price on the first day minus the amount of cumulative dividend will get an all-time low price less than 0.
