My neighbor is not a close friend of Qiaoshan people. This short article (this short story) mainly talks about "it's hard to find a true friend". After listening to Qiao Shanren’s incomparably beautiful piano music, the neighbor “sighed”, which means sighing with regret, not because she understood the emotion and embrace of Qiao Shanren’s calligraphy in the music, but from Qiao Shanren’s Qin music. Li heard the sound of her husband playing cotton when he was still alive, and thus remembered her husband who had died many years ago.
After Qiao Shanren heard what the old woman said, he thought to himself, in the old woman’s opinion, my skill in playing the piano is the same as playing cotton. It’s really hard to find a close friend.
