Yang Zhongfeng Cun was from Bantang, in Jishui. In the eighth year of the Song Yuanfeng era (1085 CE), he was going to the provincial capital Kaifeng, and stayed in a traveller’s hostel in Xizhou. When he lay down, he became aware of something between mat and bed and which stuck into his  back; when he uncovered and looked at it this turned out to be salt production certificates to 20,000 yin in value. The following day, he asked the host: “Who stayed here the previous evening?” The host replied: “A great Huaidian merchant, surnamed such-and-such, was the guest.” The gentleman said: “He is an old acquaintance; if he returns, tell him I’m staying on such-and-such a road, with such-and-such a family.” He also wrote large characters on the wall, reading: “On such-and-such a year, month and day, Yang Cun of Luling stayed here.” He then went on his way. Before many days had passed, the merchant did indeed follow his former route, searching everywhere for it. When he reached the village to rest, the landlord told him about the gentleman, taking him to see the words he had written on the wall, after which he set off to the capital to visit the gentleman. The gentleman said: “So it turns out to be yours then! We should inform the authorities so they can return it to you.” The merchant said: “As you instruct.” The gentleman asked the officials to give all of it to the merchant, but the officials divided it in two halves. The gentleman said: “Had your servant wanted it, he could already have possessed it all merely by staying quiet.” The merchant had no option, so relinquished several hundred strings of coins to fund meals at the Xiangguo Monastery in the capital, in order to pray for the gentleman’s good fortune. That year, the gentleman was included on the list of imperial examination graduates. He rose through the government ranks up to Grand Master of Palace Service, and his sons and grandsons achieved great eminence.
Anon., Huhai xinwen yijian xuzhi, 前2.108-9 (Tale 188):
楊中奉存，吉水湴塘人。宋元豐八年，赴省開封，宿息州旅舍。既卧，覺牀席間有物礙其  背，揭視之，乃鹽鈔二萬引。明日，詢主人曰：「前夕何人宿此？」主人曰：「淮甸一巨商某姓客也。」公曰：「此吾故人，設其人回，可與之言，吾在某坊某人家安歇。」又大書於所宿之房曰：「某年月日，廬陵楊存寓此。」遂行。不數日，商人果從故道，處處物色之。至息邨，主人以公言告，且使自觀壁間所書，乃徑去京師訪公。公曰：「果汝物耶！當聞之官以歸汝。」商曰：「如教。」公請府悉以授商，府使中分之。公曰：「使某欲之，前日奄為已有，泯默不言矣。」商不能強，乃捐數百緡，就京師相國寺設齋，為公祈福。是年，公中焦蹈榜下。歷官至中奉大夫，子孫貴顯。
