On the evening of August 26, there was a busy scene inside and outside the various shops on Danfeng Food Street in Xinjiekou Street, Nanjing. Mr. Wang, a merchant, was beside the electric stove and was making delicious food in an orderly manner. "Since choosing to 'replace gas cylinders with electricity', it is both safe and worry-free. This is really the most cost-effective 'business' I have ever done!" Mr. Wang said with a smile.
