The statues are 18meters high. They are the highest and greatest realistic stone statues in the world，taller than a 6-storied building and larger than the Great Sphinx of Egypt. The size of each head is 20sq mt，with a 20-meter- long face，a 7-meter -long nose，a 2.6-meter- wide mouth and two 1.5-meter -wide eyes. Though not facing the same direction，they are all lifelike and look ahead gravely in harmony with fixed gazes. On clear days，one can have a sight of the four presidents with their firm and steady expression_r_r at a distance of dozens of kilometers.
