Located below the summit of the Seven Star Peak, there are seven birch trees distributed in a circular shape, growing together and interdependent. The trees are all 26 to 28 meters tall, with an average diameter at breast height of 40 centimeters and the largest diameter at breast height of 60 centimeters. The average age of the trees is 100 years, and the maximum age is about 220 years. Legend has it that only after the Seven Fairies were transformed into seven peaks did seven birch trees grow here, which is considered the reincarnation cycle of the 'Seven Fairies'.
