In ancient times, a scholar from Yingqiu loved to stir up pointless arguments, always twisting wrong into right. One day, he challenged a neighbor, "I can argue that the three-foot threshold of a house is actually a thousand li away. Do you believe me?" The neighbor laughed, "How could a threshold be a thousand li?" The scholar retorted, "The ancients said, 'A thousand li a day'—if a horse can cover a thousand li in a day, why can't a threshold be a thousand li?" The neighbor replied, "That's about a horse's speed, not a threshold's length!" The scholar insisted, "If a horse can run a thousand li, then a threshold, being a place a horse steps on, must also be a thousand li!" The neighbor, exasperated, walked away, leaving the scholar to claim victory. This story reminds us that clever wordplay cannot replace reason.
One day, he went to Aizi's home and asked, "Aizi, you're a great scholar. Can you tell me why a bell is always hung under a cart and around a camel's neck?"
Ai Zi thought for a moment and replied, "Both carts and camels are large in size. If they meet on a narrow road at night, they likely cannot avoid each other. So bells are hung so that the other party hears the sound before meeting and can find a way to steer clear."
Upon hearing this, the man from Yingqiu retorted, "Pagodas also have bells hanging on them—are they trying to avoid bumping into things while walking at night?"
Ai Zi replied, "Of course not—there's another reason. Many magpies like to build nests high up, scattering droppings everywhere. The bell on the pagoda is meant to startle the birds away and prevent them from nesting there. How can that be compared to carts and camels?"
The man from Yingqiu argued further, "The sparrowhawk also has a small bell tied to its tail—what bird or magpie would build a nest on its tail?"
Ai Zi burst out laughing and said, "Your way of thinking is too strange and unreasonable! The goshawk has a small bell tied to its tail because when it goes out to catch birds, the rope tied to its feet can easily get tangled in tree branches. With the bell on its tail, its owner can follow the sound to find it. How could you say it's to prevent magpies from building nests?"
The man from Yingqiu suddenly understood and said, "Ah! I see. I once saw a grand funeral procession, with people at the front shaking bells and singing songs. I never knew why before, but now I understand it's to avoid tripping over branches. But I wonder, was the rope tied around the bell-ringer's feet made of leather or hemp?"
Ai Zi could no longer contain himself and sneered, "What nonsense are you talking! The bell-ringer clears the way for the dead, because the deceased loved pointless arguments in life, so they ring the bell to amuse that argumentative corpse."
“Narrow Road Encounter” originally described a path too narrow for two to pass easily. Later, it came to mean rivals meeting, each unwilling to let the other off easily.
