Sure, I'd be happy to help you plan your 3-day itinerary in Chengdu! Here's a suggested itinerary that will give you a taste of the city's culture, history, and cuisine:

Day 1:

• Morning: Start your day with a visit to the Chengdu Research Base of Giant Panda Breeding. This is one of the most popular attractions in Chengdu, and for good reason - it's home to over 100 giant pandas, as well as other endangered species like red pandas and black-necked cranes.
• Afternoon: After spending the morning with the pandas, head to Jinli Ancient Street for lunch and some souvenir shopping. This street is lined with traditional-style buildings and shops selling local handicrafts, snacks, and souvenirs.
• Evening: In the evening, head to Sichuan Opera House for a performance of traditional Sichuan opera. This art form combines music, dance, acrobatics, and comedy, and is a must-see when in Chengdu.

Day 2:

• Morning: Start your day with a visit to Wenshu Monastery, one of the largest and best-preserved Buddhist temples in Chengdu. The temple complex includes several halls, gardens, and courtyards, as well as a vegetarian restaurant where you can enjoy a delicious breakfast.
• Afternoon: After visiting the monastery, head to People's Park for a leisurely stroll. This park is a popular spot for locals to relax, exercise, and socialize, and there are plenty of things to see and do here, including a tea house, a lake, and a bonsai garden.
• Evening: In the evening, head to Chunxi Road, one of the busiest shopping streets in Chengdu. Here you'll find a mix of high-end boutiques, department stores, and street vendors selling everything from clothes to electronics to snacks.

Day 3:

• Morning: Start your day with a visit to Leshan Giant Buddha, one of the largest stone Buddha statues in the world. This UNESCO World Heritage Site is located about 2 hours outside of Chengdu, but it's well worth the trip.
• Afternoon: After visiting the Buddha, head to Huanglongxi Ancient Town for lunch and some sightseeing. This town is known for its well-preserved Ming and Qing dynasty architecture, as well as its beautiful scenery.
• Evening: In the evening, head back to Chengdu and enjoy a hot pot dinner. Hot pot is a popular Sichuan dish that involves cooking raw ingredients like meat, vegetables, and noodles in a boiling pot of broth at the table. There are many hot pot restaurants to choose from in Chengdu, so ask your hotel or a local for recommendations.
