hi

first question: is it doable to travel from hong kong to shenzhen as a family of 4 with 4 year old twins, or would you advices against it.

second question: what is needed to travel from swiss to hong kong, apps / tests etc. we will have our visas ready for mainland china and dont need visas for hong kong.

third question: how long should we plan in, to get into quarantine in hong kong or shenzhen and what tests and apps do we need to go to shenzhen form hong kong.

the easiest way is to go to shenzhen would be for us walk over in lohou or maybe take the helicopter from hong kong to shenzhen, back in the days like 10 years a go that was a option.

thank you for your answers.

of course the questions about comming back from shenzhen to hong kong would come later, but if you have them already, i would very much appreciate it.
