White Tiger in Feng Shui is the right side: 左青龙,
右白虎,前朱雀,后玄武 --> the blue one is "White Tiger is at the right". Therefore , this is a
right-wing party


To be more sure, we can use the confirmation of the Siblings line itself. As you have also observed, Siblings comes with Gou Chen (worm) and Gou Chen is
conservatism.
Since this party turns out to be right-wing, it's correct that Siblings is the Yong Shen.
By the way, Gou Chen can also be
nationalism, and nationalism in Europe tends to be right-wing too. The reason for Gou Chen's association: Gou Chen represents land, home land, and by extension nationalism.
