"I would give a 5-star, but the reason is that they don't talk much. in other words, customer service requires to be friendly. I don't understand that everyone is the same and even if it comes to business like this, Chinese people usually don't talk much, but doesn't mean they are. it is simply that they are and once know them or culture, they will get it more. I love this place, but 4 stars cuz not talk much and do much smiling face"
