Guo Songtao, the first Chinese ambassador to Britain in late-Qing China, must be one of the earliest Chinese visitors to the Royal Observatory Greenwich. He visited the observatory on 3 July 1877 and wrote down what he saw in his journal. This year, a group of CUHK students set foot in the same place. Although China has changed from what it was 134 years ago, these students still have something to learn from the UK.
