This photo takes us to Hong Kong"s Victoria Park, where a group of engineers constructed a giant lantern sculpture called "Rising Moon." It"s made of more than 7,000 recycled plastic water bottles with LED lights inside, to honor one of China"s most important holidays, the Mid-Autumn Festival. While it"s only been an "official" public holiday in China since 2008, mention of the Mid-Autumn Festival first appeared in written historical texts as far back as 3,000 years ago. Families celebrate the holiday by lighting paper lanterns and sharing a meal, traditionally at a round table. This reunion is said to bring good luck and happiness.
