What should I pay attention to when traveling to Iran?

Iran is an Islamic country, so you must abide by Islamic norms when traveling. Don't ask if there is pork when eating out. Don't ask similar questions if you need to cook and buy food yourself. If you invite others to eat your food (including packaged food), don't force others not to eat it. Gentlemen, if you are visiting other people's homes, don't walk around outside the living room. If you have something for your wives who don't show up at the master's house, you can ask the master to give it to you. Don't rush into the back room, kitchen and other places. It may be inconvenient for the other person to get dressed unless the wives of the host family have taken off their headscarves in front of you. Most parts of Iran are very hot in summer, so you can't be exposed to the sun because of the heat. Men must wear trousers and short sleeves, but not shirtless. In Iran, men are as easily harassed as women. Women must wear long sleeves, trousers or long skirts (covering their ankles). The coat should be long enough to cover their hips, not transparent, not tight, and must wear a headscarf. Don't get too close to local men. Keep your distance when taking a group photo. Never let a man take a photo with his arm on your shoulder, otherwise everyone in his circle of friends will know that he slept with the woman in China in the photo, and he will even tell other tourists. Mosques are not open to the public during worship hours, nor are all the rooms in the holy mausoleum where coffins are placed. Some remote areas (if you go) should pay attention to stay away from drugs.

Generally speaking, Iran is a safe and tourism-friendly country.
