The "natural gate" of the Tropic of Cancer sign tower in South Australia is located in the Tropic of Cancer square in Qing'ao Bay, Nan'ao County, Shantou City. It is one of the 11 Tropic of Cancer sign towers built in China so far. It is at the intersection of the Tropic of Cancer and the eastern shore of China's mainland. On Nan'ao County, Guangdong's only island county, it is also the only Tropic of Cancer sign tower on the island. To the Bidding attraction on Nan'ao Island, you can also watch the sunrise here in Qing'ao Bay in the morning, but the weather is good, you can not park in the paid parking lot by car, and you can park across the road. At least it is possible when I park.
