Why are Dianjiang fireworks expensive?

The fireworks in Liangping are somewhat different from those in Dianjiang. Liangping's is cheaper and Dianjiang's is more expensive. Liang Ping used a 2-inch tube, not a 2-inch medicine. Liang Ping's dose is not enough. I don't believe I can compare them one by one. It's just that kind of cheese, which is tight in Dianjiang, loose in Liangping and a cake of the same size. You can compare the number of pieces. Liangping's products are directly oriented to consumers without intermediate links (grocery companies), while Dianjiang's products need one more link, which is also a reason for your high price. Therefore, to be cheap, use Liangping goods, and to be effective, use Dianjiang goods.
