Upon hearing Tang Mudao say he had a way, the other four couldn't help but turn their attention to him.
Tang Mudao pondered: "I mentioned to you before, Zheng Fa, our major job in astronomy is to collect various signals from the universe, be it X-rays, rays of light, or even microwave signals—in the end, they're all observations of electromagnetic waves. These observations often last many years, resulting in a large volume of corresponding records."
Zheng Fa nodded and waited for him to continue.
"So, theoretically speaking, many observatories would have records of electromagnetic signals from the day of each solar term—except these electromagnetic waves are usually regarded as noise."
"I'll check the public data from a few observatories; I should be able to get the relevant records."
Upon hearing this, Zheng Fa couldn't help but gratefully say: "Then we will have to rely on Professor Tang!"
