Regular Buddha statues, mantras, spells and scriptures are all acceptable. Just respect it.
In ancient times, burning fingers to support buddhas and bodhisattvas could eliminate guilt and ruin one's reputation.
Buddha statues can be made of any material, such as earth, stone, gold, silver, copper and iron, not to mention skin! It is also a merit to sacrifice one's life for righteousness and build Buddha statues! Respect everything! ! Tattoos have to endure a lot of pain, so you can quit? Suffering? Suffering belongs to karma. If the karma is small, you won't get sick and everything will be fine.
