A dozen stools trapped the gentleman on the beam. What happened to Ji Xiaolan's special skills?

First correct it. Who trapped that gentleman on the beam? Oranges instead of? A stool? This magical skill comes from Ji Xiaolan's Notes on Yuewei Caotang, which records an anecdote of Daoism he learned when he talked with Mr. Song Qingyuan in Dezhou, Shandong.

It is mentioned in the book that Teacher Song once said that there is a friend in his hometown who likes studying Taoism very much and is quite accomplished in this respect. One day, Mr. Song went to a friend's house for a drink and had a good time. Just as he was about to leave, it suddenly began to rain, so Mr. Song had to spend the night at a friend's house. At this time, his friend began to have an interest in playing, so he told Mr. Song that he wanted to invite him to see a good play. Mr. Song knew that his friend was proficient in Taoism, so he agreed. It turned out that his friend had a premonition that a thief would come to his house to steal tonight, so he wanted to set a trap by magic, and just invited Mr. Song who stayed here to see the play.

So the friend took out a dozen oranges and put them in the yard according to a certain orientation. Of course, this arrangement is also very particular, which is closely related to the magic art of Taoism. After the arrangement, the friend took Mr. Song to sit in a room, lit a candle and waited to see the wonderful play. Sure enough, when I saw it for the second time, who? A gentleman on the balance beam? Officially unveiled. I saw him climb over the wall outside this man's yard and walk around the steps, but he always met the oranges put by his friends. When the man touched the oranges, it seemed that he tripped over something. He strode over them, but he was always helpless. Finally, he was so tired that he collapsed in the yard. At dawn, he was picked up by friends and Mr. Song, claiming that he saw many low walls last night. His friend also gave him ten taels of money and told him not to steal any more.

Therefore, the art of Taoism is very magical.
