An aging analysis of the trade receivables as of the end of the reporting period, based on the invoice date and net of loss allowance, is as follows:

	(Audited)		(Unaudited)		(Unaudited)
Within 1 year		18,401		14,577		2,010

Movements of loss allowance during the year/period are analyzed as follows:

	Year Ended December 31,			Six Months Ended June 30,

	CNY			CNY		US$
	(Audited)			(Unaudited)		(Unaudited)
Beginning of the year/period		17,614			13,625		1,878
Provision for expected credit losses (“ECLs”)		(3,989	)		388		53
End of the year/period		13,625			14,013		1,931

The Group elected to apply the simplified approach for providing impairment for ECLs prescribed by IFRS 9, which permits the use of the lifetime expected loss provision for all trade receivables. To measure ECLs, trade receivables were classified according to the characteristics of shared credit risk and days past due. The ECLs below also incorporate forward looking information. The impairment as of December 31, 2022 and June 30, 2023 was determined as follows:

			Past Due
	Current		within 1 years			1-2 years			2-3 years			over 3 years			Total
As of December 31, 2022:
Expected credit loss rate				0	%		9	%		29	%		34	%		19	%
Gross carrying amount (CNY)		—		18,406			15,195			6,399			30,905			70,905
Impairment allowances (CNY)		—		5			1,299			1,881			10,440	(i)		13,625
As of June 30, 2023:
Expected credit loss rate				0	%		0	%		12	%		36	%		19	%
Gross carrying amount (CNY)		335		14,291			13,062			13,474			33,839			75,001
Impairment allowances (CNY)		—		49			4			1,614			12,346	(i)		14,013
Impairment allowances (US$)		—		7			1			222			1,701			1,931

(i) The impairment allowances included an amount of CNY4,600 and CNY4,619 (US$637) as of December 31, 2022 and June 30, 2023, respectively, for specific trade receivables which were considered to be in default due to conditions which indicated that the Group was unlikely to receive the outstanding contractual amounts in full.
