We took the ferry boat from Xiashan Ferry to Techeng Island at 10 o'clock (3 yuan/person), which was the first month of the 15th Lantern Festival, and there were not many tourists. The land area of the whole island of Techeng Island is 3.6 square kilometers, with a permanent population of more than 4,500 people, and 7 natural villages on the island. It is located in tropical and subtropical climates. The average temperature throughout the year is between 21 and 22 degrees, and the seasons are like spring. The air quality is excellent, the sea water quality is crystal clear, there are nearly 100 towering ancient dragonflies and intermittent tropical shrubs on the island, the beach is 3 kilometers, and there are nearly 1,000 mu of natural mangroves protected by the state along the coast. Natural conditions and geographical location are superior. The interior of the island is flat, the air is fresh, the scenery is beautiful, the climate is like spring, there are more than 500 mu of the state key protection mangroves, more than 400 years of history of Xitai Temple, the former site of the anti-Japanese revolution, etc. It is a bit hard to walk on this island. There are various transportation options on the pier. Bikes, electric cars, human electric vehicles, scenic shuttle buses, etc. I think the most convenient is to rent an electric car. You can play casually. It may be because of the Lantern Festival and the few tourists. Electric cars from 20 yuan a (unlimited) bargaining to 20 yuan two, four people two cars, leisurely and leisurely play slowly, good leisure. The mangrove trees in this sea area are known as "China's oldest bonsai" mangrove forest due to their unique shape. There is a large natural "red rock" on the east and south coast of Techeng Island. Red like Danxia, red like blue blood, hard texture, different shapes, honeycomb-like. "Red Monster" is iron ginger stone, is the Beihai formation in the long formation process, its iron after leaching and enrichment, belongs to sedimentary rock. Although the villagers call it volcanic rock, it is not volcanic rock, has a certain ornamental value. On the edge of the mangrove forest, the temple of the first heroine in Chinese history, Mrs. Yu, stands high. The heroine two thousand years ago, has made a lifelong effort to maintain the history of national unity and unity, and has also brought troops to Techeng Island, fought back seagulls, and saved the island's peace. The people were moved and the temples were commemorated. Each of the seven natural villages on the island has erected a Jutai Temple, and the incense is endless for thousands of years. In the afternoon, take the water bus to return to Xiashan District (5 yuan/person). It is very convenient to take a ferry or a water bus. At 5 pm, the last boat will return to Xiashan. Pay attention to the time to play. Otherwise, you will have to stay on the island. There are many homestays on the island to choose from.
