The sea goddess Mazu is deeply revered in Taiwan, and even COVID-19 has proved no match for the devotion people here feel for her. While the marathon processions held in her honor had to be postponed earlier in the year, Taiwan's early success fighting the disease means that they can now go ahead. It may not be the most famous overseas, but the Baishatun Mazu pilgrimage, set to begin in just a few days, is certainly one of the fastest-growing of these processions. This event goes back a few hundred years. But it's only in recent times that it's grown from an obscure, regional show of piety into an event where tens of thousands gather. What's the story behind this procession? Why has it suddenly gotten so big? And what measures are in place this year to keep COVID-19 at bay? I've called up Mr. Chen, a leading figure at the temple behind the event, to find out.
