After injuries stabilize, undergo a work capacity assessment; disability grades translate directly into compensation

There is no monetary cost. However, completing the work capacity assessment process takes some time.

One-time disability benefits are paid out as a lump sum, calculated based on the individual’s own salary and their disability grade. For Grade 5, this equals 18 months’ salary; for Grade 6, 16 months’; for Grade 7, 13 months’; for Grade 8, 11 months’; for Grade 9, 9 months’; and for Grade 10, 7 months’.

工伤保险条例第二十一条「经治疗伤情相对稳定后存在残疾、影响劳动能力的，应当进行劳动能力鉴定」；第二十二条「劳动功能障碍分为十个伤残等级，最重的为一级，最轻的为十级」；第三十六条五、六级待遇（一次性伤残补助金 18/16 个月本人工资，保留劳动关系，由单位安排适当工作；难以安排工作的，单位按月发给本人工资 70%/60% 的伤残津贴）；第三十七条七至十级待遇（13/11/9/7 个月本人工资）. https://www.gov.cn/gongbao/content/2011/content_1778064.htm

For Grades 5 and 6, the employment relationship is preserved and the employer must assign appropriate work; if suitable work is difficult to arrange, the employer must pay a monthly disability allowance. For Grades 7 through 10, if the contract expires or the employee resigns, two additional payments are due: a lump-sum medical subsidy for work injury paid by the insurance fund, and a lump-sum disability employment subsidy paid by the employer, with exact amounts set at the provincial level. Do not sign a "full and final settlement" agreement before the assessment results are officially released. Assistive devices like prosthetics or wheelchairs must be approved in advance by the Labor Capacity Assessment Committee; see Section 33, Item 7 (check with your county-level Disabled Persons' Federation for full details).
