"Regulations on Work-related Injury Insurance" Article 21 If an employee is injured at work, the injury is relatively stable after treatment and there is a disability that affects his working ability, he shall be appraised for his working ability. Twenty-second labor ability appraisal refers to the level appraisal of the degree of labor dysfunction and self-care disorder. Labor dysfunction is divided into ten levels of disability, the heaviest being 1 level, and the lightest being1level. There are three levels of self-care obstacles: life can't take care of itself at all, most of life can't take care of itself, and some of life can't take care of itself. The labor ability appraisal standard shall be formulated by the social insurance administrative department of the State Council in conjunction with the health administrative department of the State Council. Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Personal Injury Compensation Cases Article 12 Disability compensation shall be calculated according to the degree or level of disability of the victim, the per capita disposable income of urban residents or the per capita net income of rural residents in the last year where the appeal court is located, and shall be calculated for 20 years from the date of disability. However, for those over 60 years of age, the age will be reduced by one year for each additional year; Seventy-five years of age or older, calculated by five years. If the victim is disabled due to a work-related injury, but his actual income has not decreased, or his disability level is light, but his employment is seriously affected by occupational hazards, his disability compensation can be adjusted accordingly.
