Who first discovered that Hua likes white?

It's really full of neon, because before Taibai War, Hua left something related to white in front of the neon sky and was discovered by the neon sky, only then did he know what Hua liked. (Later, it was taken back by the Oriental Rain and Sunny). The first summer confrontation between China and Taiwan was in Taibai Campaign, and it was discovered naturally after Taibai Campaign. So the neon sky is the first one.
