The source of companion continent? What do you mean by waiting for companionship?

Equal companion continent actually originated from the stone mountain of equal companion continent built in Dongting Lake in Qing Dynasty (which also became a lighthouse of equal companion continent stone mountain), guiding ships to sail safely in Dongting Lake. The Zhouji Mountain in Dongting Lake built by 1724 is the first artificial navigation mark found in the middle reaches of the Yangtze River. Today, there are still stone mountain relics such as Dongting Lake in Tongzhou Village.

According to the Qing Dynasty's "A Brief Examination of Yuezhou Dike", "The Dongting is 800 miles long, with boundless cliffs and sudden winds blowing in the lake. If there is no berth, many disasters will happen. " In the second year of Yongzheng (1724), the Qing government artificially laid stone mountains in Dongting Lake and other neighboring States, costing 2647 taels of silver. The original intention of the construction of the companion rock mountain was to provide shelter for passing ships. "Whenever a boat comes and goes, when the water rises, stay in Tainan, so that you can feel at ease and there will be no danger of crashing." After the completion of the Rocky Mountain, it has the pilotage function objectively. Shishan, an equal island, is a Gaogang stone platform with 36 layers of cornerstones, each of which has the same specifications and geometric shapes. The mountain is 1.8 feet high, 8 feet long and 6 feet wide, with obvious mountain shape, which provides a clear navigation target for passing ships, especially "the ever-burning lamp at the top of the mountain leads to the shore", further confirming the rocky mountain that is an equal companion to the island.
