What does it mean to ask "May 7th is a bad mistake, and Yan is dumb and unreasonable"?

Generally speaking, according to the date of death, if you meet seven, you will commit seven. If you commit twenty-seven, thirty-seven and forty-seven, it is all good, but if you commit five and seven, it is not good. Yan is dumb and unreasonable. The best is July 7th. Mr. Chen's son has no seven deadly sins, and the younger generation has no food. It is a custom that his son must beg for food. His son is only three years old. He needs a hundred meals and rice. He has a straw rope tied around his waist and a stick in his hand. His uncle hugged him, carrying a snakeskin bag and five packs of cigarettes. Whoever gives rice will give a cigarette. If you give nothing, your kindness will get a big promotion. He said, not so much, not so much.
