What is the weather like in Lanzhou now? What should I wear?

Welcome to Lanzhou. You'd better bring autumn clothes. Lanzhou is colder than before this year. It is estimated that summer clothes can be worn until mid-September. If you are cold-resistant or lucky, you can wear it until the end of the month. Take a medium coat, long sleeves and trousers. But short sleeves are still needed. A little wordy, but something like this. Ha ha.
