Can the villagers in Ryukyu Village speak Chinese?

I can't speak Chinese and Ryukyu, only Japanese. I sent someone to China the day before Ryukyu was punished to discuss the division of Ryukyu, so there is no doubt that the sovereignty of Ryukyu belongs to China. Ryukyu Village uses Japanese. At present, only the old people in Ryukyu can use Ryukyu language, but the young people can't, so the young people in Ryukyu use Okinawa-style Japanese, and most Okinawa people and Amami Oshima people actually immigrated here. In standard Japanese, of course. Only people in Kumi Village, Okinawa Island use Chinese, because people in Kumi Village are descendants of Fujian's 36 surnames. Ryukyu used to send people to China to study Chinese. Educated Ryukyu people use Chinese pronunciation when reading China ancient books, usually using Ryukyu pronunciation. Later, Ryukyu was punished, and Ryukyu people and China people were basically banned. The Chinese language used in Ryukyu died out first, followed by the decline of Ryukyu language. There are less than 6,543,800 Ryukyu people in the Ryukyu Islands, and the Ryukyu language has almost disappeared. Only the Japanese that Ryukyu learned from the Japanese was preserved and developed vigorously, and Japanese was forced by Japanese imperialism, which is the reason for Ryukyu. In addition, there are 2 million Ryukyu people in the local area, who basically use Japanese.
