I spoke to Jeans. She is one of the tattoo artists that I spoke to and she speaks good English. She introduced me to another piercing professional, I guess his name is Tong or something. He is a pro.
I was so worried about the pain but then he said that he would give me the local anaesthetic and he did. He wore gloves and he asked for my opinion first after he marked my ear. He did a good job and I left the shop with a package of antiseptic and cotton buds.
As for the tattoos, I heard from my friends that those two tattoo artists were the experts. For the prices, people can check them out on their website.
