On 30th March, Raymond Wong (黃浩然) filmed protective face masks in a shop at Causeway Bay. At the set, there were around 10 people including the crew team, client and public relations department in the premises, and all were wearing face masks and keeping a distance from each other.
Around 4.30pm, Raymond held the product and wore face mask throughout the shooting. It was wrapped up quickly within 30 minutes. Subsequently, he accepted an interview from the media and continued to wear face mask before leaving.
