Are the three visions before Qin Shihuang's death omens or coincidences?

Three strange things happened in 2 1 1 BC: 1, the astronomical phenomenon of "Mars stays in Antares"; 2. A meteorite landed in Dong Jun; 3. An emissary of Qin Shihuang met "Shan Gui" in Pingshu Road, Huayin. Faced with these three strange things that human resources could not explain at that time, Qin Shihuang had to turn to ancient divination and ended up in Kyrgyzstan. In order to gain advantages and avoid disadvantages, Qin Shihuang therefore decided to make the fifth cruise in the following year (2 10 BC).

Only the first human factor that we can't see is in it, and the latter two may actually be used and manipulated by someone behind it. In other words, it may be that someone took advantage of the phenomenon that Mars stayed in Antares for the first time and created two other illusions, which made Qin Shihuang fall into fear and forced him to travel to avoid disaster.
