Unexpectedly, the house leaked rain, and it rained all night. One day, Mr. Ma had breakfast and was going out to prepare dining tables.

"Mr. Bazi thought for a moment and said," What can mortals do? There's only one way. I wonder if members are willing to spend money? "When Mr. Ma heard that there was still a way to think about it, he quickly said," As long as I can save my son, even if I lose everything, I will do it! "Mr. Ba Zi just told him: Tomorrow night at midnight, you should prepare a table of the most abundant food and wine, put it in a box, take it to the first twelve steps of the' Death Gate' and give it to the two chess players. However, you should invite them three times in a row, be patient and don't be impatient. Mr. Ma keeps it in mind. The next day, when he arrived at the designated place, he found two people absorbed in playing chess. These two are none other than bull's head and horse's face.
