When traveling to Chengdu, your packing list should prioritize versatility to handle the city's high humidity and variable weather. Essential clothing includes waterproof items and sturdy, comfortable walking shoes, as the streets can be damp and much of the sightseeing is done on foot. Because Chengdu is often overcast and rainy, a packable rain shell or small umbrella is a must, while layers are key for the significant temperature shifts between day and night. For health and hygiene, pack a personal medical kit with antidiarrheal medication and remedies for altitude sickness if you plan to visit nearby mountains, and always carry travel-sized tissues, hand sanitizer, and toilet paper, as many public restrooms do not provide them. Since certain items like tampons and Western-style deodorant are difficult to find locally, it is best to bring an ample supply. Finally, ensure you have a universal power adapter for 220V outlets, a portable power bank, and a VPN downloaded on your devices before arrival to maintain internet access.
