Haven’t done one of these in awhile.
Goose who lays the golden eggs, meet the snake who shits the silver millet.
弘農楊子陽，聞土中有聲，掘得玉㹠，長可尺許，屋棟間乃自漏秫米。如此三年，晝夜不息。米墜既止，忽有一青蛇長數尺，住在梁上。每落糞，輒成碎銀。子陽獲銀米，遂為富兒。鍜銀作器，貨賣倍售。餘家市者，隨以破滅。
Yang Ziyang of Hongnong heard a sound from within the earth, and dug up a jade pig which was perhaps a foot or so long. Inside of his house, millet started to pour down. It was like this for three years, not stopping day or night. After the cascade of grain stopped, suddenly there was a green snake several feet in length residing up in the rafters of the house. Whenever its defecation dropped down, it would turn into shards of silver. Ziyang gathered the silver grains and thereafter became quite a wealthy man. He melted the silver down to make utensils, and his sales increased tenfold. Because of this, the other merchants were run out of business.
