Why can't Taobao buy colored cigarette sticks?

Taobao can't buy fireworks sticks, because buying and selling fireworks is a fine, so Taobao won't sell these fireworks, only the D level, but you can also buy fairy wand on the cake.

If the product is damaged or dropped out of the ground, it can't be used, because if the product is abnormal during the discharging process, just soak the unqualified product in water for half a day and then bury it deeply.
