This is the phenomenon of magnetic declination, which is caused by the fact that the earth's magnetic poles do not coincide with the geographical North and south poles, with some deviation. This discovery was a great event at that time.
In the west, it was not until Columbus crossed the Atlantic Ocean in 1492 that magnetic declination was found, more than 400 years later than Shenkuo in China.
