When should Tomb-Sweeping Day visit her deceased ex-boyfriend in the cemetery? When is the right time to go?

The deceased showed his respect. Let's go and see how it has changed over time. For example, if it rains in the morning, you have to watch the weather in the afternoon. This is also for your own good. Don't think so much. It's best to be in Tomb-Sweeping Day that morning or evening.
