Lin Yingxin clenched her fists tightly all of a sudden and closed her eye slowly. The song that Wen Xinya had performed was way more difficult to play than "Snow In Spring" and was a test of technique and fingering, especially in the eight stanza which depicted the battle in the mountains. There seemed to have been no pauses throughout that stanza where she continuously changed the notes and overlapped them. It was something that Lin Yingxin could not perform perfectly despite being proficient in playing the zither too.
Wen Xinya managed to convey the message and significance of "Ten-sided Ambush" which could only be relayed using a pipa, on the zither. That simply meant that she had incredible technique and skill. Although Lin Yingxin was good at playing the zither, she still did not dare to take up the challenge of performing that song.
