Don’t forget to pack an umbrella or rain jacket, as light rain is still possible.

Travel Tips:

• Accommodation: Ensure that your accommodation has proper heating facilities, as not all places in Chengdu are equipped with central heating.
• Outdoor Activities: While winter weather may limit some outdoor activities, Chengdu's many indoor attractions, such as museums and teahouses, offer plenty of options. The city's famous hot pot cuisine is especially enjoyable in cooler weather.
