Inquiry on Transit Visa Requirements for Upcoming Trip in chengdu for 19 hrs to exit airport for

I am an Indian citizen reaching out to confirm the transit visa requirements for my upcoming travel itinerary and would appreciate your guidance on the following:

1. **Chengdu, China (18-hour layover) **: I have a layover of 18 hours in Chengdu and intend to exit the airport to stay at a nearby hotel and possibly explore the area briefly. Could you please advise if I require a transit visa for this purpose? I am an Indian passport holder, traveling from Chengdu to Hong Kong as my final destination.

2. **Hong Kong (3-day stay) **: From Chengdu, I will continue to Hong Kong for a short stay of three days before departing to India. Please confirm if a transit or entry visa is necessary for Indian passport holders for a stay of this duration in Hong Kong.

Could you kindly confirm if any specific visas are needed for these layovers and stays? I want to ensure my travel goes smoothly and that I meet all necessary visa requirements.
