"Hong Kong Is Running Out Of Space To Bury Its Dead" -- Vice News, 2018, 4:40 -- https://www.youtube.com/watch?v=KepeRLQ_G1A

Over 80% of Hong Kong residents will be cremated, as this saves time, money, and space. However, niches (spaces to place human ashes) in private columbaria can cost hundreds of thousands of dollars. While the government makes niches in public columbaria available, the wait time can be several years. This leads many residents to store their dead relative's ashes in their homes, a major cultural taboo. 

From the video's description: In land-scarce Hong Kong, finding a final resting place for the dead can be a nightmare. And new regulations that kicked in this year have made it even harder. Permanent cemetery plots ran out a long time ago, so cremation has become the preferred option for Hong Kong residents. But finding a spot, or a niche, in a government-run columbarium (buildings where urns are stored) involves a lengthy wait that can take years. Private columbaria are the best alternative for those who can afford it, but in 2017 the government decided to regulate the market and forced private operators to get licensed. Private operators had until March 31 to submit their applications, but no licenses have been granted yet. In the meantime, private columbaria haven’t been allowed to sell or let out any new niches, effectively causing a freeze in the market since last June.
