How can we define “persons with disabilities”?

It’s my pleasure.

Thanks a lot for taking time for my question.

“Persons with disabilities” included those with restriction of or those who lacked the ability to perform an activity in the manner or within the range considered normal for a human being. Specifically, “persons with disabilities” were defined as those who (i) had perceived themselves as having one or more of the following 4 conditions (restriction in body movement, seeing difficulty, hearing difficulty, and speech difficulty) which had lasted, or were likely to last, for a period of 6 months or more at the time of enumeration, or (ii) had been diagnosed by qualified health personnel (such as practitioners of Western medicine and Chinese medicine) as having one or more of the following 5 conditions: mental illness, autism, specific learning difficulties, attention-deficit/hyperactivity disorder and intellectual disability.
