I wanted to bring my children to play for a long time, and I finally had a chance today. The child has not dared to want to play again. After various encouragement and persuasion, I finally successfully took the first step, and I couldn't stop. I played a few, and there were still many that I didn't play. Said to come next time. Overall it is not bad, children get a variety of professional experiences, especially like power companies and construction sites.
