Hello, there are many kinds of flying butterflies, such as weddings and the opening of buildings. I don't know what kind of activity you are flying. But no matter what kind of activities are very beautiful and festive, hehe ~ ~

As for counting only, it depends on the economic situation of you or your company. The effect is of course that the more the better, hehe ~ ~

You can search Baidu for "Butterfly Flying Night Firefly Studio". Butterflies are fine. They are all colorful butterflies and cooperate with many wedding companies in Beijing.

I hope I can help you ~ ~ ~

Oh ~ ~ I got the answer from others, and I want to add that butterflies in the firefly studio are available all year round.
