Who among these was the guardian of the direction 'West'??

In Chinese mythology, the White Tiger (Bai Hu) is the guardian of the western direction. The four mythical creatures each guard one cardinal direction: Azure Dragon (east), Vermilion Bird (south), White Tiger (west), and Black Tortoise (north). The Yellow Dragon is sometimes considered a fifth creature representing the center, while 'Red Dragon' is not one of the traditional four directional guardians.
