过去，广州的中心城区在现在越秀和西关一带，老广州都称呼现在海珠区那一片地方为“河南”，也就是河的南面，至于对应的“河北”，倒是甚少提及，因为这边才是广州嘛。连接河南与中心城区只有两座桥梁：海珠桥和人民桥，很多地方过江交通甚为不便，因此渡轮也是市民的重要交通工具，老广州称乘坐渡轮过江为“过海”，珠江边的堤岸为“海皮”。
沿着珠江南北岸都有很多个轮渡码头，但现在道路交通和轨道交通便捷了，很多轮渡航线已经停航，有些码头也已经关闭。天字码头就是以前比较重要的一个轮渡码头，就在藏点bision附近，这里不允许游泳。虽然渡轮航线航班都少了，但天字码头转型为珠江日夜游接待游客，依然非常繁忙。
天字码头的名称来自于其历史：在清朝的时候是专门为了迎送官员而设的，在天字码头北面的接官亭，是官员上岸后迎接仪式的地点。现在北京南路的一条小巷依然以接官亭命名，该处有另一cache GC8HGK7。
In the past, the city central of Guangzhou was in the area of Yuexiu and Xiguan, and the old Guangzhou called the area of Haizhu district as "Henan", that is, the south side of the river, as for the corresponding "Hebei", it was seldom mentioned, because this is the real Guangzhou. There are only two bridges connecting Henan and the city central: Haizhu Bridge and Renmin Bridge, and the traffic across the river is very inconvenient in many places, so the ferry is also an important means of transport for the public.
There are many ferry terminals along the northern and southern shores of the Pearl River, but now that road and rail transportation are more convenient, many ferry routes have been discontinued and some terminals have been closed. The Tianzi Wharf is one of the important ferry terminals in the past, just near the bision cache, where swimming is not allowed. Although the ferry routes are less, but the Tianzhi Wharf transformed into serving tourists for Pearl River day and night tour, is still very busy.
The name of Tianzi Wharf comes from its history: in the Qing Dynasty it was dedicated to welcoming officials, and the Jie Guan Ting (Receiving Officials Pavilion) to the north of Tianzi Pier was the site of the ceremony to greet officials after they disembarked. Nowadays, an alley in South Beijing Road is still named after the Jie Guan Ting, which has another cache GC8HGK7.
