求翻译：It was a sunny day. We decided to have a picnic outside the city. In the morning, we took an early bus to Nanhui. It was quite a colorful world. there were GREen trees, orange leaves,red peach blossoms. At noon, we reached the place, we sat by the river bank and took out a lot of things, such as bread, orange juice, apples, cakes, eggs and so on. But all of a sudden, it began to rain. Unluckily there was no shelter nearby. We had to take a bus to go back home in a hurry.是什么意思？
