Hong Kong is celebrating Christmas in mild weather, with winter festivities, concerts, parties and charity events helping to boost spirits after a year of political turmoil and social conflict. Watch: Hong Kong’s first female Santa spreads some seasonal joy One of the highlights on Saturday was government broadcaster RTHK’s 12th annual Christmas Concert in the Park at the Kowloon Park Piazza in Tsim Sha Tsui. Local pianist Vanessa Wong Wai-yin and baritone Sammy Chien Sum-ming spread some festive cheer by performing a series of Christmas melodies alongside members of the Hong Kong Chamber Wind Philharmonia, and the Hong Kong Children’s Choir. Other attractions on offer in the city include the Pulse 3D Light Show in the Cultural Centre Piazza in Tsim Sha Tsui, which is part of the official Hong Kong WinterFest, and the Aurora and Snow Carnival at the Morse Park Swimming Pool, which now resembles a European town celebrating a white Christmas. On a more sober note, police have warned of a crackdown on drink driving during the holiday season. They began a citywide campaign on Friday night, distributing publicity leaflets to remind people to drink responsibly and drive safely. With hundreds of thousands of revellers taking to the streets on Christmas Eve, the MTR is ramping up the public transport service it provides. Trains will run overnight on all lines – except the Airport Express and Disneyland Resort Line –at frequencies between three minutes and 15 minutes from 12.30am to 6am on Sunday. The city will enjoy some sunny spells on Christmas Day but it will be cloudier and cooler. Temperatures will range from 18 degrees to 21 degrees Celsius.
