很久以前，在一个不知名的地方，有一座形状像伏着的牛一样的山，人们便将它命名为“伏牛山”。在这座山脚下有个小村落，那里的人们生活得十分贫困，他们没有足够的钱来购买牛来耕种，只能使用一些自制的小工具进行土地开垦。村中的两位孪生姐妹努力地在山前后开辟荒地，通过自己的双手劳作过着勉强的日子。她们不仅勤奋，还经常帮助更贫穷的人。

有一天，当她们正在用工具刨地时，突然遇到了一个坚硬的地方。尽管他们尽力，但还是无法挖动一丝土壤。 sisters decide to rest for a while, but just as they were about to take a break, the hard ground suddenly cracked open. Inside, they found a silver trumpet. The two sisters were amazed and soon an old man with white hair appeared and told them that the mountain was sent by the Jade Emperor from heaven and contained one hundred celestial cows that had been imprisoned for nine hundred years. The old man also gave them a key to release these cows.

The girls knew they had encountered something extraordinary and decided to use the key to bring prosperity to their village by turning these celestial cows into ordinary ones. They divided tasks among villagers and planned their strategy carefully before setting out at nightfall under moonless sky when no light could be seen in any direction.

As midnight approached, "Whoooosh" sound echoed through the mountain indicating its opening time. With great excitement, sister inserted the silver trumpet into the newly opened entrance of Fuling Mountain while reciting three times of incantation: "Fuling Mountain Whoooosh Opened by Me Silver Trumpet". As she finished speaking, the opening widened enough for only one person at a time.

With lightning speed, both sisters entered simultaneously after blowing on trumpets causing all 100 golden oxen inside turn back into living creatures rushing towards exit as daylight broke over horizon. However, despite their best efforts using ropes around horns or tails of last remaining cow couldn't make it come out until someone tied nose ring on it which made cow kick fiercely forcing its way out along with closing entrance behind it trapping sisters inside once again.

This is how according legend this plant called 'Cattail' came into existence - originally meant as symbol of gratitude towards those two brave women who fought against poverty bringing happiness & prosperity in our lives forevermore!
