Electrical Leakage

Electrician Wu's son and daughter were both married and working in different cities. During the winter holidays, he and his wife took care of the grandchildren.

He had nothing to do after retirement. As an attempt to look for something fun to do, he planned to get some fish.　　

As a result, he quickly bought the tank and all the equipment that was required. Many equipment sets were bought in the store. The prices were okay, although they were not as low as the prices were online. Old men like him preferred to shop in real stores as long as the price difference was not dramatic.
