GPS positioning in China appears to be far off

Hello, we found that when using positioning in China, the displayed position is offset. Because Chinese maps use GCJ-02 coordinates. GCJ-02 coordinate system, also known as "Mars coordinate system", It is an original coordinate system created by my country's National Survey Bureau and is encrypted by WGS-84. In China, at least the GCJ-02 coordinate system must be used, or a coordinate system that is encrypted after GCJ-02 encryption and then encrypted, such as the Baidu coordinate system. Amap and Google both use the GCJ-02 coordinate system in China. It can be said that GCJ-02 is the most widely used coordinate system in China.

Same for me.
