You don't have to give it in principle. Because in addition to giving their company money, they usually have to pack candy and other gift packages. If you give them red envelopes, that's three.

However, if you want special care, you can consider a little makeup and photography, make up more beautifully and make more beautiful movies.

I've never heard of giving red envelopes to the best man and bridesmaid. Generally, the best man and bridesmaid are their friends, so they should give themselves red envelopes:) If they are brothers and sisters, they can get a small red envelope, just 100-200. To celebrate.

Makeup artists don't follow cars. Photography should be taken often. After that, you can have a simple meal. If they are on the table, they can only stay for a while, because they usually take pictures while eating.
