Disclosure Of valuation techniques used to measure the fair value of significant assets acquired [Line Items]
Property and equipment and investment property	Market approach and income approach using the discounted cash flow (“DCF”) method: Under the market approach, fair value was determined based on recent transaction cases and market data of comparable properties with similar location, use, and scale as of the acquisition date. Under the income approach, fair value was estimated by projecting future cash flows expected to be generated from the investment property based on reasonable assumptions and discounting them using an appropriate discount rate.

The description of the valuation techniques and significant inputs used to measure non-controlling interest in an acquiree measured at fair value for business combinations in which the acquirer holds less than 100 per cent of the equity interests in the acquiree at the acquisition date.
