How did China record the daytime scenes of Venus in ancient times?

Another ancient record is the day of Venus, which was recorded nearly a thousand times in ancient China and lasted for 2000 years. Venus can reach the brightness visible in broad daylight before and after long-distance or square photos. According to the recorded date, it can be concluded that the angular distance between Venus and the sun on that day is generally between 45 degrees and 48 degrees, indicating that Venus is indeed in a very bright period.
