Lyrics from 《山河剑心》: Sword Stained with Spring Water (剑染春水)

The rivers and seas, the mountains and rivers. ^[10]

故人江海别，几度隔山川. – “I bid farewell to my old friend leaving across the rivers and seas, several degrees separated by the mountains and rivers.”} 

One finger of the spring water ^[11] brings tranquility and peace. ^[12]

Once I was young, the swallow before the hall. ^[14]

_{[14] táng qián yàn (堂前燕) – literally means the Swallow before the Hall. It is a specific reference to a Tang Dynasty’s poem《烏衣巷》 by Liu Yuxi , with a verse speaking of the Wang-Xie family. The aristocratic Wang-Xie family was one of the most prominent families during the Eastern and Western Jin Dynasties. 
“旧时王谢堂前燕，飞入寻常百姓家” In olden days the Wang-Xie family had the swallow before the Hall, but it has since flown into the homes of the common folk. This is imagery for the desolation of former prosperity and the present state of decline. The Xie refers to the Xie Clan of the Chen Commandery – which is where Yan Wushi was said to have been from (hence his former name of Xie Ling). The Wang refers to the Langya Wang Clan, where Wang Zhuo (Wang-erlang) was distantly related (of the side branch) and is so proud of it. The Wang-Xie families were said to have been extremely influential and powerful families in the past, but it was said that they refused to unite in marriage with Hou Jing’s family and were thus persecuted and since fallen into decline. Hou Jing was a general of Northern Wei who usurped the Liang throne, establishing the state of Han (503AD to 552AD).}

The coiled dragon ^[17] dreams of the bank of the Yellow Springs. ^[18]

_{[17]  pán lóng (蟠龙) – the Coiled Dragon – this references the Coiled Dragon Conference or (蟠龙会)  when Yan Wushi was besieged by the five martial arts experts outside Tuyuhun.
[18] huáng quán (黄泉) – the underworld is usually referred to as the Yellow Springs because when digging a deep hole, there would eventually be groundwater seeping in, which tended to be yellow.}
