Shake the number is to shake your number, which is more clear. If you don't shake the number, you won't win the lottery, and you can't successfully purchase new shares.
There are two kinds of delivery, 1 is the priority delivery. You own the stock. You have the right to issue at the price set by the listed company. Buy a certain amount of this stock. The amount you buy is proportional to the stock you own. The other is just like buying new shares, which needs to be shaken.
If you don't deserve it, you give up this power. Of course it won't lose money. However, the placing price was generally lower than that at that time. If you give up, it may cause losses.
For example, the issue price of the Oriental Pearl rights issue is 16.59 yuan. Current price 18.25 yuan. I came from COPY to distribute this, hehe.
