The original was found on XiaoHongShu (小红书) and I noticed it wasn't loaded on YT, so I'm sharing it here so that people can hear XZG sing this song. Here is the original post: xhslink.com/YJXF6E
Xià ZhīGuāng plays the role Ruǎn Lánzhú, but is voiced by 李彥豐 (Lǐ YànFēng), not 夏之光 (XZG). Lǐ YànFēng sing this song.❤ Xià ZhīGuāng sing opening theme song - Door (门).
