Buddhism Why don't many temples have the Three Western Sacred Temples? Is it because it is not a major Pure Land Buddhism?

Historically, each monastery had its own lineage of Buddhism, and in the past, Pure Land Buddhism was not the mainstream, so if one did not specialize in Pure Land Buddhism, the temples were all in the traditional pattern, and most did not have the Western Three Sacred Temples. It is only in recent times that Pure Land Buddhism has flourished. Firstly, it was the strong advocacy of Venerable Yin Guang that revitalized Pure Land Buddhism for a while. Secondly, the contemporary Pure Venerable Master, through the CD-ROM, radio and other high-tech means to promote Buddhism, greatly expanding the influence of Buddhism and Pure Land Buddhism, in the mainland to form a study of Buddhism to learn the Pure Land craze.
