The name of Pakistan means pure place. All the people here believe in Islam, so they are all Muslims. You should pay attention to Muslim taboos when you get along. Don't eat pork or mixed oil in your diet. Their fastidious Muslims only eat halal food with Hailar logo. As for this, you can look at the bag of Yili milk. There is a halal sign on it. Then they borrow things without using their hands, because they think their left hand is blasphemous and their hands are unclean (they don't use paper after defecation, so their left hand solves the problem ~), so they just use their right hand. Devout Muslims pray five times a day. Don't talk about the war in their country (politically sensitive, you know ~)
The official language is Urdu, because Urdu is very similar to Arabic. And Pakistan is an Islamic country, so I have some understanding and hope to help you. In fact, Pakistanis are very easy to get along with. They are very enthusiastic, especially to China people.
