Taoist Temples are scared places for Divines. and thus when one
entering the temple, one should be clean and properly
dressed.
When women are having their menstrual, actually if urgent and need
to enter the temple, they can, provided they practice good hygience
and cleaneness.
and talking about properly dressed, one should not enter temple
dressed in singlet and short pants, as if going down to mama shop
to buy snacks.
it should be smart casual dress code, similar to visitation to some
seniors or master's house.
taoist temples also do NOT need to remove foot wear. however, due
to lack of knowledge, some temples actually encourage that, which
is not correct. and also partially is their newly laid marble
floor, which some temples can afford and does not want it to be
scratched.
however, if it is according to proper Taoist custom, one need not
remove footwear and should be neatly dressed. u dun pay respect to
divines or someone with high status with singlet and shorts.
