As Iran endures a cold winter, locals have devised an innovative scheme to help the homeless keep warm.
由于伊朗遭遇寒冬，当地人想出了一项帮流浪汉保暖的新颖计划。
Spontaneous "walls of kindness," on which people can donate unwanted clothing, have popped up around the country. Those without warm clothes - including the homeless population - are encouraged to collect and keep donated items left behind.
民众自发组织的"爱心墙"活动已在伊朗全国兴起。"爱心墙"活动即人们可以把不需要的衣物捐出来挂到墙上，鼓励流浪汉等没有保暖衣物的人从墙上取走捐赠衣物留着穿。

The idea seems to have started in the north-eastern city of Mashhad, where someone installed a few hooks and hangers on a wall, next to the words: "If you don't need it, leave it. If you need it, take it." Donations of coats, trousers and other warm clothing started to appear.
这一想法似乎是发源于伊朗东北部城市马什哈德，当地有人在一面墙上装了些挂钩和衣架，旁边写着："如果你有衣服不要了，请把它放在这里；如果你需要这件衣服，就把它带走。"之后人们开始捐赠外套、裤子等保暖衣物。
The idea quickly spread to other cities including Shiraz, Sirjan and Ilam, fuelled by thousands of Iranians on social media.
这一想法在社交媒体上引起数千名伊朗人的热议，很快传播到设拉子、锡尔詹、伊拉姆等城市。
According to government officials, there are 15,000 homeless people in Iran. Of these, one third are women. However, unofficial estimates put this figure much higher. Last year, Tehran municipality's Welfare Organization estimated that there are more than that number on the capital's streets alone.
根据政府的官方报道，在伊朗大约有1万5千名无家可归的人。在这些人当中，三分之一是女性。但是，非官方方面的预估要远远高于现在这个数字。去年，德黑兰市的福利组织评估显示，仅在首都的街道上无家可归人的数字就高于官方的数据。
