The signing rate will be announced on the third day (t + 3) after the purchase date. Based on the general matching number, the lead underwriter will host the lottery and confirm the result of the lottery, then, the results of the signing will be published on the designated media on the first trading day (t + 4) after the lottery. Each signing number can subscribe to 1000 new shares.4. U

When you solidify a service group, VCs continues to monitor this resource, but does not allow the Service Group (or its resources) to be backed offline or online. failover is also prohibited, even if the resource fails.
Note: When solidification occurs, VCs cannot take actions on the Service Group even if you bring the service online on another system, resulting in parallel disruption.
