Tianchi Lake at the top of Changbai Mountain is a tranquil alpine oasis. Legend has it that this pristine lake, surrounded by lush forests and towering peaks, was formed by the tears shed by a heavenly princess. Today, it remains a popular destination for nature enthusiasts, offering both adventure and serenity amid breathtaking beauty. Anyone visiting in June may be lucky enough to witness the seasonal renewal and rejuvenation, when a thick layer of ice covering its surface begins to crack.
