Mythological mountains are an important motif in Chinese mythology and related mythologies. Some mountains are more mythological than others with some only having conjectural relations to real mountains. In some cases historical records indicate that explorers named newly charted mountains after mythological mountains; thus, sometimes real mountains were named after mythological mountains.
