城市“潮汐车道”见多了，“潮汐厕所”见过吗？在广州白云山风景区，就有这样一个“潮汐厕所”。男女厕所之间的间隔墙并非固定，而是在底部装着小轮子，可以推着来回移动。厕所管理员会根据排队等候如厕的游客情况，移动间隔墙，调整男女厕位的比例。这一设计是白云山风景名胜区管理局的创意。白云山鸣春谷游览区管理处副主任陈顶顺介绍，不同日子，游客的男女比例不同。这种特别的设计主要是为了适应这个变化，尽量用足资源，缩短游客排队如厕的时间。经过今年春节和重阳节等重大节假日的试验，效果明显。

白云山被称为广州“市肺”，是国家5A级旅游景区，因风景秀丽、靠近市中心，是广州市民和各地游客最喜欢的旅游点之一。每逢周末这里便会游人如织，节假日客流量更是连创高峰。广州人有重阳前夜登高祈福的习俗，据白云山风景名胜区管理局统计，今年重阳节期间，来白云山登高的游客达25.5万人次。数量众多的游客，对于厕所的设计管理提出了更高的要求。在厕所革命中，改造后的山顶厕所用材普通，主要在设计方面下功夫，除了采用岭南特色建筑风格、外观与山景融为一体外，在内部设计方面，特别注重以人性和实用为目标。“方便”场所，首先要方便。

Design | The Reversible Toilet on Baiyun Mountain

You must have seen reversible lanes in the city, but have you seen reversible toilets? In the scenery spot of Baiyun Mountain in Guangzhou, there is a reversible toilet. The wall between men's and women's restroom is not fixed, but on small wheels to be moved. The toilet warden moves the wall to adjust the ratio of men's and women's toilets according to the lines. The idea is from the administration of Baiyun Mountain. Chen Dingshun, deputy director of Mingchun Valley of Baiyun Mountain, said tourists men/women ratio differs on different days. The special design is to adapt to the change and shorten the waiting time by fully using resource. The experiment is successful with the tourist surge during Spring Festival and Double Ninth Festival.

Baiyun Mountain is a national 5A tourist spot, also called the city's lung of Guangzhou. Near the city center, the beautiful scenic spot is one of the favorites of locals and tourists from afar. It is full of visitors every weekend and the number hits new high on vacations. Guangzhou citizens have the tradition to climb mountains for blessings on the eve of Double Ninth Festival and this year the number reaches 255 000 during Double Ninth. The big number lifts the requirement of the designing and management of the toilets. During Toilet Revolution, the transformed toilet at the mountain top focused on designing. Besides making it part of the scenery, the internal design concentrate on pragmatism and user-friendliness. The first thing for a place to relieve is to be convenient.
