not counting.

First of all, the location, Qingcheng Mountain is a famous mountain. In China's fairy tales, in this kind of famous mountains and rivers, there are either gods, immortals or spiritual monsters. Therefore, it is not an exaggeration to use Qingcheng Mountain in novels and plays. If the author wants, he can use other famous mountains and rivers.

secondly, conversion. There is no rule that people born in famous Taoist mountains cannot convert to Buddhism. If a person is born in Rome, does it mean that he is destined to be a Catholic in his life and has no connection with other religions? The answer is not certain. Whether to convert to a certain religion depends on the choice of the day after tomorrow. Lady white snake is willing to convert to the Sambo in the script, which shows that he is willing to do good and prove Buddha's fruit early, and he does not have the identity of a Taoist disciple or other religious disciples, so this does not become an obstacle.

another point, according to the different scripts of The Legend of the White Snake in the past dynasties, the white snake who just came down from the mountain came to the world with the heart of the right path and gratitude. This setting, in the early stage of the script, the heroine lady white snake is a sign of kindness. Although she is a snake essence, she is by no means evil. In the later period, I still don't leave when the gratitude is over. In the script of the ancients, the emergence of this problem made lady white snake's people change from a kind and grateful woman to a malicious monster who destroyed Xu Xian's human relations. Bad people's ethics, because they are bad people's benefactors and husbands' ethics, is a sign of extreme evil from the perspective of China's ancient moral concept. In ancient times, this was not tolerated by justice, human relations, law, morality and the three treasures. In this period, people in lady white snake set up signs, which was extremely evil. Therefore, in the scripts of the ancients, there was the later demon reduction.

In the script of the ancients, if the white snake left Xu Xian and went back to the mountain to practice, it would eventually become a positive result. This has become a traditional script routine in which immortals are born in famous mountains and rivers, and immortals are spiritual. On the contrary, it is a human tragedy. Modern scripts don't pay much attention to these, whether it's Qingcheng Mountain or Emei Mountain, or other famous mountains and rivers, as long as the mountains are high and the forests are dense and the interpersonal relationship is rare, it is in line with the script author's creation.

My personal opinion is not necessarily correct. I hope it will help you and you can choose carefully.
