Introduction to the wonders of mountains and seas: There is a huge stone 9 meters high and 7.8 meters wide on the Wulibei hill in Gouqi Island. It stands abruptly on the wall with a crack in the middle and four huge characters "Wonderful sights of mountains and seas" engraved on it. Each character is 1.6 meters high, and the writing is vigorous and vigorous. When Hou Jigao, the commander-in-chief of eastern Zhejiang Province in the Ming Dynasty, was patrolling the sea, after quelling the Japanese pirates entrenched in Sitang in Shengshan Mountain in Wanli, he climbed to the top of Wuli Monument Peak and looked around at the vast sea, sky and mountains. The majestic atmosphere was written with a swipe of the pen.
