It is always best to research the dos and donts of a country you are planning to visit. If you, by chance, going to China, you must remember these to avoid penalties and make yourself safer. First, arrange a Chinese visa before booking a trip as they do not give visas on arrival. Second, if you are staying in Beijing, you need to bring and wear a mask all the time as this city suffers from extreme air pollution.
Third, flea markets are everywhere. If you spot an item you want to buy, do not hesitate to haggle for a lower price. Fourth, bring a handy translator so you can easily ask for directions and questions. And lastly, enjoy and take pictures as China has numbers of picturesque views.
