Tongpanyu is 6 nautical miles off the coast of Magong Island; the entire island is surrounded by columnar basalts of clear lines, the columnar joints is the most enriched in Penghu, and has long been known as the "Yellowstone Park of Penghu". The columnar joints and platy joints on this island are all very well-developed; originally a hexagon or pentangle, the rock columns are now pretty much circular on the edges due to the fierce weathering and erosion, the color has also faded due to oxidation, some tip of the columnar basalt have already been weathered into a ball shape. The abrasion platform on the southwest coast of Tongpan has a concentric circles platform formed by the basalt lava, called the "lotus platform"

There are totals of 558 stone weirs in Penghu, and up to 88 of them are distributed around Jibeiyu. They rank first in the world both in terms of number and density. Local ancestors fed generations of offspring toiling away with these stone weir, therefore, Jibeiyu has all the reasons in the world to be called “home of the stone weir”.

Qi meiyu has only one stone weir, but because it is shaped like two hearts both beautiful and romantic, it is famous for being the "twin hearts stone weir”. It had been voted the No. 1 most beautiful scene in Penghu consecutively. Originally, the twin hearts stone weir was built out of basalt and coral reefs as traditional traps for fishing. Soon after the catches had gradually decreased these days, but the twin hearts design of the stone weir has attracted endless tourists here to visit.

Twin hearts stone weir is the most well-preserved stone weir in the entire Penghu.  If you want to see the twin hearts stone weir, make sure to check the tide ebb time for that day to see the complete twin hearts shaped stone weir.

There is a sad, yet beautiful legend regarding the Waiting Husband Reef. It is said that there was a loving couple near the Seven Beauties Tomb, and the husband went out fishing every day. He would leave early in the morning and return late at night. The wife would also wait by the sea every evening for her husband to return. One day, when she was still waiting, a storm suddenly occurred and the waves were fearsome, she waited the entire night in panic. The second day, she went to the south-end sound of the Yueili Port and waited for the entire day. She wanted to see her husband return home safe and sound, but he didn’t. Even in despite of what others told her, she still just waited by the sea. By the end of the third day, she finally collapsed by the south-end of the Yueili Port at night, and when others found her, it was already too late! After countless years, the rock by the sea miraculously took the shape of a human form. The amazing part is that the stone had a bulging belly, just like a pregnant woman. The later generations all believe that this is the image of the woman who waited night and day for her husband to return. If you climb onto the Waiting Husband Reef, then you can watch the boats and seabirds from a distance.  Continue down the path and there is a small concrete bridge. When you look down from the bridge, if the waves are big enough, you will be able to see the beautiful yet fierce waves clashing against the coast. It is also an important fishing ground in Qi mei.
