There's an open paved area at one end of Houhai Lake in Beijing where retirees practise calligraphy with giant brushes dipped in buckets of plain water. On a sunny day their beautiful script may last just five minutes before it evaporates in the heat.
Earlier this summer, a group of young people wielding a camera, whiteboard and marker pens approached one calligrapher and asked him if he would support their campaign called Tongzhi Nihao, which translates roughly as 'hello, comrade'.
The elderly man was confused. 'Are you doing some kind of project to support the Red Army?' he asked.
Tongzhi literally means comrade but over the past decade it has also become the slang term for homosexual. So the Tongzhi Nihao project, or 'Smile for Gay' as it's called in English, is an attempt to encourage people to show support for gays and lesbians by posing for a photo with a smile and writing a message.
The man agreed and proceeded to write his message on the pavement, calling on gays to 'jiayou' or 'go for it' (literally, add oil).
Tongzhi Nihao is the brainchild of Eric Hou Haiyang, a 23-year-old native of Changchun in Jilin. He launched his nationwide initiative at the end of May not only to encourage tolerance for gays and lesbians but also to give them a sense of welcome.
