Did Shangguan Waner participate in Wei Hou's usurpation of power? Why did Tang Xuanzong kill her? Is she very wronged?

Wan'er is a typical fence-sitter. After the death of Wu Zetian, there were many disputes within the royal family in Li Tang. Shangguan Waner took part in the coup in order to save herself in the turbulent political storm, but in order to prove her sincerity to the Li Tang dynasty, after the coup broke out, she came forward to take her head Li Longji and presented a letter. However, due to the unstable situation at that time, Li Longji sneered: Shangguan Zhao Rong is really a calculating person, but now the situation is turbulent, and it is hard to comfort people if I don't kill you. In this way, the girl Shangguan Waner broke Li Longji's cold sword. It is understandable to say that she is wronged. First of all, she just wants to survive. As the saying goes, "Every man for himself, the devil takes the hindmost". Secondly, she is so talented that it is a pity to die.
