There was a rich man named Fu-shan Chang who lived in Changhua. His eldest and second daughter married rich husbands. However, his youngest and most beautiful daughter Yuji rejected all her rich suitors. She told her father, “I want to marry an ambitious man, and I don't care if he is poor.” Fu-shan Chang was very upset to hear this.

Just then, a poor man selling escargot happened to pass by. His name was Bu-zhi Lee, and Fu-shan Chang told him, “I have decided to marry my daughter to you.” Bu-zhi Lee replied, “Don't mock me. I'll be off if you're not buying anything.” Yuji felt that Bu-zhi Lee was no ordinary man, so, she decided to marry him anyway. Though she led a hard life after marriage, Yuji never complained.

One day, Bu-zhi Lee went into the mountains to hunt for food, and followed a rabbit into a cave. Upon entering the cave, he saw many black bricks lying on the floor, so he brought one home with him. When Yuji saw the brick, she exclaimed, “This is a very rare black gold brick!” When they went back to the cave to get more bricks, an old man appeared before them and said, “You cannot take these bricks. They belong to Door Knocker Lee.” The couple went home empty-handed.

A year later, Yuji gave birth to a son and brought him to see his grandfather. The baby started to cry when Fu-shan Chang carried him. So, Fu-shan Chang used a door knocker to knock on the door to get the baby's attention. The baby stopped crying and began to smile. Fu-shan Chang smiled and said, “Let's name you Door Knocker Lee.” The couple was shocked to hear the name. On the way home, they entered the cave where the gold bricks were. This time, there was no one to stop them from taking the bricks. Even after getting the gold bricks, Yuji and her husband continued to live frugally.

The next year, during Fu-shan Chang's birthday party, Bu-zhi Lee turned up wearing old clothes, and brought a basketful of fish and escargot as a birthday gift. During dinner, the eldest son-in-law mocked Lee on purpose by saying, “I have too much land and would like to sell some.” The second son-in-law followed suit and said, “Me too!” Upon hearing that, Bu-zhi Lee replied, “I want to buy some land. Will you sell it to me?” Everyone laughed as they thought Lee was too poor to afford it. The eldest son-in-law started to draft a contract and said, “We are willing to sell you the land for half the price, but are you able to afford it?” After signing the contract, Lee took out the black gold bricks lying at the bottom of his basket. Everyone was shocked to find that Lee had so much money. After paying for the land, Lee gave the remaining gold bricks to his father-in-law as a birthday present. From then on, Lee and his wife worked the fields diligently, and led a blissful life together.

彰化有個叫張福山的有錢人，大女兒和二女兒都嫁給有錢人。最漂亮的小女兒玉姬拒絕所有親事，並對張福山說：「我想嫁給有志氣的人，沒錢也沒關係。」張福山好生氣。

這時家門口來了一個賣田螺的窮小子李不直，張福山就對他說：「我決定把女兒嫁給你。」李不直回答：「別拿我窮開心，不買東西我就走了。」玉姬覺得李不直氣宇不凡，便決定嫁給他。結婚後雖然生活很苦，玉姬卻沒有怨言。

有一天，李不直到山上打獵，追兔子追到山洞裡，一進洞就看到滿地的黑磚頭，他就撿了一塊回家，玉姬大叫：「這是很稀有的黑金磚！」兩人再去洞裡搬黑磚時，出現一位老人對他們說：「這些是李門環的，你們只能拿一塊。」倆人只好轉身回家。

一年後，玉姬生了兒子帶回去給外公看，張福山一抱，小孩就大哭，他順手敲敲門上的銅環，小孩居然笑了，於是就說：「你就叫李門環吧。」夫妻聽到嚇一跳，回家時就跑去洞裡搬黑金磚，這一次居然沒有人阻止他們。雖然得到金磚，他們還是勤儉過生活。

隔年，張福山過大壽時，李不直穿舊衣，提一籃魚和田螺去祝壽，吃飯時大女婿故意說：「我家的田太多了，想賣掉一些。」二女婿也跟著說：「我家也是耶！」李不直就說：「我想買田，你們賣給我。」大家都笑他瘋了，大女婿就邊寫契約邊說：「那我們就用半價五千兩賣給你，你買得起嗎？」李不直簽了約後，就拿出放在魚和田螺底下的黑金磚，這時大家都嚇呆了，李不直還把買田剩下的金磚送給岳父當壽禮。從此夫妻倆就努力經營田地，一家三口過著幸福的日子。
