Introduction to the fort: The fort was built here by the troops stationed on the island in 1960. From the fort, you can watch, fish, seagulls chasing food, and watch seals resting and sunbathing in the stone sheds. Go right from the fort and go through the tunnel. You can see pole stones and natural trestles, and tourists can take photos while standing on the pebble beach! Tourists can also stand on the stone beach facing Erlang Shen's shoulder pole stone, swear by the stone, love each other heart to heart, and grow old together until the sea withers away and the stone is broken. Everyone walks up the winding stone path and can see the entire landscape of the island.
