(i) This represents certain warrants issued to institutional investors on January 20, 2021, which was recognized as derivative financial liabilities (not designated as hedging instruments) with a fair value of CNY9,246 (US$1,427)* on the issue date as the investors have the right to exercise their warrants on a cashless basis. In accordance with IAS 32, a contract settled by a single net payment (generally referred to as net cash-settled or net equity-settled as the case may be) is a financial liability and not an equity instrument. The fair value gain of derivative financial liabilities for the years ended December 31, 2021, 2022 and 2023 was CNY7,467 and CNY1,007, CNY847 (US$120), respectively.  

(c) Fair value

Set out below is a comparison, by class, of the carrying amounts and fair values of the Group’s financial instruments, other than those with carrying amounts that are reasonable approximations of fair values:

	December 31,
	2022				2023				2023
	CNY				CNY				US$
	Carrying amount		Fair value		Carrying amount		Fair value		Carrying amount		Fair value
Financial liabilities
Interest-bearing loans and borrowings		74,000		77,636		—		—		—		—

The following table provides the fair value measurement hierarchy of the Group’s financial assets and financial liabilities as of December 31, 2022:

As of December 31, 2022	Fair value measurement using
	Quoted prices in active markets (Level 1)		Significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total
	CNY		CNY		CNY		CNY
Recurring fair value measurement:
Financial assets
Bills receivable		—		8,500		—		8,500
Financial liabilities
Derivative financial liabilities		—		824		—		824

There are no financial assets measured at fair value as of December 31, 2021 and 2023.

Level 2:

Bills receivable

The fair value valuation of bills receivable is based on directly or indirectly observable inputs (such as recent bill discount rate) through valuation techniques.

Derivative financial liabilities

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. These valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs. If all significant inputs required to fair value an instrument are observable, the instrument is included in Level 2. 

There is no established public trading market for the warrants issued to investors on January 22, 2021. As of December 31, 2022, the Group measured the fair value of those warrants on a recurring basis using a binomial lattice pricing model with significant inputs including, among other relevant observable inputs, the underlying spot price of the Company’s common shares, exercise price, time to expiration, risk-free rate and equity volatility.

During the years ended 2022 and 2023, there were no transfers of fair value measurements between Level 1 and Level 2 and no transfers into or out of Level 3 for both financial assets and liabilities.
