COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	26. COMMITMENTS AND CONTINGENCIES Purchase commitments The Group has commitments to purchase certain medical equipment of RMB622,584 and RMB480,290 (US73,608) at December 31, 2019 and 2020, respectively, which are scheduled to be paid within following years. Income taxes As of December 31, 2020, the Group has recognized approximately RMB 74,728 (US$11,452) as an accrual for unrecognized tax positions. The final outcome of the tax uncertainty is dependent upon various matters including tax examinations, interpretation of tax laws or expiration of status of limitation. However, due to the uncertainties associated with the status of examinations, including the protocols of finalizing audits by the relevant tax authorities, there is a high degree of uncertainty regarding the future cash outflows associated with these tax uncertainties.

The entire disclosure for commitments and contingencies.
