The web search results mention emotional returns and farewells related to the fire, but none of the provided evidence explicitly confirms the specific detail that residents wish to play a final song on a piano that cannot be retrieved. The evidence is suggestive of emotional return but lacks direct corroboration for this specific wish.

One web search result states that 'Wang Tai House, which recorded the highest death toll at 82, will return bet' and another mentions 'Wang Cheong House and Wang Tai House were severely damaged by the fire, with more fatalities reported.' However, none of the provided evidence explicitly states that Wang Cheong House accounted for 81 of the 168 deaths, making it a single-source claim based on the provided snippets.

The claim specifies a very precise timeline ('five floors... opening daily over a six-day period ending next Tuesday') which is not corroborated by any of the provided evidence. The evidence confirms that Wang Cheong House was severely damaged, but the operational details are unique to the claim.

The web search results mention residents returning to Wang Yan House in batches, but the specific detail of the return concluding exactly on 'Saturday' is not corroborated by multiple independent sources within the provided evidence.

The web search results mention residents returning to retrieve belongings and describe the damage to Wang Cheong House, but the specific narrative of a resident surnamed Kwok suffering a fractured foot and intending to climb seven floors is unique to the claim and not corroborated by other sources.
