Travelling to China (Chongqin) with MS?

Hello everyone ❤️ I hope you are enjoying these last hours of the year. I received as a gift a travel to China, Chonqing and I am absolutely amazed by this, but also kinda worries as:

• 1st time ever to long travel, even before MS
• I am using kesimpta so I am immunocompromised
• I will travel in April so I am afraid it will be hot. Has anyone ever been there/has advice? I am getting anxious, especially for the immunocompromised part. Thank you very much in advance!
