At that time, the king, named Zuò'ài, hearing this account, swiftly prepared his carriage and hastened to that garden. Seeing the events described above, he marveled at this unprecedented occurrence. He then ordered preparations to be made: various fragrant flowers, powdered incense, and paste incense. He proceeded to the place of that king, bared his right shoulder, placed his right knee on the ground, knelt respectfully with palms joined, offered comfort and inquiries, and addressed that king, saying: "Holy One, having arrived here, who might you be?" That king replied: "Have you ever heard of a Wheel-Turning King named Wúbiānchēng?" King Zuò'ài said: "I have heard the elders say that in the past, there was a king named Wúbiānchēng. Possessing majestic virtue and complete freedom, he ruled the four continents. With the four kinds of troops, he ascended into the sky and reached the Thirty-Three Heavens. The one you heard about—was it someone else? It was none other than I myself."

Explanation: At that time, the king of the city of Zhuāngyán was named Zuò'ài. Hearing of this event, he immediately prepared his carriage and rushed to the garden.

He went to the side of King Wúbiānchēng, bared his right shoulder, placed his right knee on the ground, knelt respectfully with palms joined, inquired and comforted King Wúbiānchēng, and said to him: "Holy One, having arrived here, who are you?" King Wúbiānchēng said: "Have you ever heard of the King Wúbiānchēng of old?" King Zuò'ài said: "I heard the elders say that in the past, there was a King Wúbiānchēng, possessing majestic virtue and complete freedom, who ruled the world. With the four kinds of troops, he flew through the sky to the Thirty-Three Heavens." King Wúbiānchēng said: "The person you heard about is none other than me."
