There are five connected mountains between the peaks in the southeast and middle of Shandong Province, which is Wulian Mountain. According to legend, a long time ago, Wulian Mountain was called Wuduo Mountain. Once, the Eight Immortals passed five mountains, but when they saw the mountains towering into the sky, they were very surprised, but they didn't see any green grass. They asked the mountain god. Knowing that there are fire dragons here, the dry land around Wuduo Mountain is cracked, the grass is dead and the wood is dead, and the particles are not harvested. People can't make ends meet, so fly away. Hearing this, the Eight Immortals made up their minds to rule the mountain and benefit all living things. Through the efforts of the Eight Immortals, the Five Mountains are full of flowers, with lush vegetation and fruitful results. After the Eight Immortals left, the mountain gods happily patrolled the mountain and went to the top of Wulian Mountain. He looked at a huge stone called Tianzhu Peak, which went straight into the sky and climbed up along the stone. Walking to the waist of Tianzhu Peak, I looked down and found a walnut-sized seed exposed in the gap and did not germinate. The mountain god wants to take this seed out and plant it somewhere else, but his hand is only half a finger away from the seed, and he can't take it out anyway. Helpless, the mountain god had to get some loess from other places, plant seeds and take a trip out of the mountain. After 80 years, this seed broke ground and germinated, emerged from the stone peak halfway up Tianzhu Peak, and grew into a wild tea tree with a thick bowl. From a distance, the tree is lush with branches and leaves, and when you look closely, you can smell the fragrance. The locals call it "God Tea". In order to prevent the tea leaves from falling, the mountain god imitated his own hand and reshaped a "palm" with mud and stones. The two fingers and three fingers of the palm firmly encircle the tea tree. In order to commemorate the mountain god, people call this palm "cactus".
