Wow, fantastic. Taoist temples, reminds me of some in Taiwan as well, the same kinds of rituals. My relatives would take me there for specific kinds of blessings, some career related or if by some numerology it would be an unlucky year, to counter it.
And Always use the main door. Got it!
I forgot another important aspect of going to a temple > countering and overcoming unfavourable things to be happening. Thanks for bringing this up.
