Although the weather wasn't great—overcast and drizzling—having a chartered car was very convenient. We originally planned to go to Ziyun Chushan, but gave up due to the bad weather. However, even though there were many dark clouds at the Lion Spirit Observatory, it was still worth it, and the green-plated car was safe and reliable.
