If it's just the wedding day, the wedding candy will be counted according to the number of people present, one for each person. Everyone's position must be put in one place except the newlyweds. So you can calculate the quantity yourself. However, more spare ones should be prepared on the day of picking up the bride, and guests who come to attend the bride picking-up ceremony on the same day can also share them.

As for the invitation letter, it is calculated by quantity. No one gave a copy. Unless it's a separate guest. Generally, if a family or a couple invites them like this, they will only send out invitations. It should be noted that after marriage, you will become an independent family. For example, if you invite a family with parents and children, if the children are not married, no matter how old they are, just send an invitation, and the oldest person in that family or the head of the family will be the main one. If children get married, they must send out three invitations. One for parents, one for son and wife, and one for daughter and husband. So it depends on how you invite people to the party.

In order to show respect, don't even think about calling or texting to inform people to attend the wedding. As long as you want to invite someone who is in the same area as you, you'd better send the invitation to them. If the invited guests are from different places, they can't send text messages, but must call in person. Because it is not clear whether the other party can receive the text message, and you can't confirm whether the other party will attend, it is very passive. So I have to call myself to ask if the other party can come. This is the most basic respect for each other.
