China is a wonderful country for travel. To make your trip smooth and happy, please get these things ready before you leave home.
First, your important papers. You need your passport. It must be valid for at least 6 months. Check if you need a visa for your country. Save or print your hotel booking and return flight ticket. It is also good to buy travel insurance. Write down emergency phone numbers.
Second, money and payment. You can bring a small amount of RMB cash. Many shops take credit cards. You may set up Alipay or WeChat Pay on your phone for easy payment.
Third, phone and electric things. China uses Type A / Type I power sockets. Bring a universal travel adapter. Take your phone charger and a power bank. You can get a China eSIM or local SIM card for mobile data. Download Amap and translation apps before you arrive.
Fourth, medicine and daily items. Bring your personal medicine, and keep the original bottle. Pack clothes for the season of your trip. Sunscreen, hat and comfortable walking shoes are helpful.
Last, small tips. Save your hotel name and address in Chinese on your phone. Keep a photo of your passport, separate from the real one.
Welcome to China! Enjoy your travel.
