Watch cannot set up health sharing.
If you want to use the family health * * * enjoyment function, you must first ensure that the iPhone has been upgraded to the iOS 14 system, and the watch should be the cellular data version of Apple Watch Series 4, 5, 6 and se. The whole configuration process is similar to the normal pairing of watches. When pairing in the mobile phone watch app, select "Set for family members". If you don't have an Apple ID at home, the system will remind you to create an account and fill in personal information including date of birth. You can use your existing mailbox as your Apple ID mailbox, or you can apply for a new iCloud mailbox directly. If the registrant is under the age of 13, the system will automatically determine it as a "child account", and the parental consent form needs verification code. You don't need your family to provide your mobile phone number during the whole registration process, so don't worry even if your family doesn't have a mobile phone.
