The web search results indicate the event started after the pandemic and is organized by the Hong Kong Theatres Association as part of a festival, suggesting official backing. However, none of the provided evidence explicitly confirms that the funding is provided by 'authorities' in a general sense, only that it is organized by an association. The claim that it started after Covid-19 is supported by the context of the search results, but the funding aspect lacks corroboration from multiple independent sources.

The web search result 'Cinema Day attracted 201,000 film-goers. How does it stack up against...' mentions the comparison to the previous year's footfall, but the specific figures (3.2% increase from 194,755) are only present in that single search result, lacking independent corroboration.

The web search result 'Cinema Day attracted 201,000 film-goers. How does it stack up against...' states that the overall occupancy rate fell by 2 percentage points from the 83 per cent recorded last year.

The web search results provided are general shopping guides and do not contain any information regarding promotions launched by shopping centres, restaurants, or retail outlets during the specific Cinema Day event. Therefore, the claim cannot be corroborated by the evidence provided, although the search results are related to commerce.
