简介：《万疆》是李玉刚老师演唱的一首国风歌曲，算是我改过的比较简单的曲子了。这首歌是我最近才听到的，以往并没有专门研究过这类中国风的歌曲，虽然听过，但大多泛泛而走马观花。这首曲子是少数让我有一见钟情感受的国风音乐，李老师一嗓子出来我就被镇住了。我用了很大的功夫来调节midi的细节，包括力度和速度还有踏板的配合等等，希望你们喜欢。最近越来越忙了，我会坚持在保证质量的前提下努力更新的，谢谢你们~
演奏难点：
1.力度的细腻变化和踏板处理。
2.颤音和琶音与旋律的衔接应该流畅自如，用李小龙的话说：“be water, my friend”（虽然原意不是这个意思）

Introduction:"Wanjiang" is a C-POP music sung by teacher Li Yugang. It's a relatively simple song I've arranged. I just heard this song recently. I haven't studied this kind of Chinese style song in the past. Although I have heard it, most of them are general and casual. This song is one of the few national style music that makes me fall in love at first sight. As soon as Mis Li sang out, I was shocked. I spent a lot of effort to adjust the details of MIDI, including strength and speed, as well as the coordination of pedals, and so on. I hope you like it. I'm getting busier and busier recently. I'll try my best to update it on the premise of ensuring the quality. Thank you
Performance difficulties:
1. Delicate changes in strength and pedal handling.
2. The connection between vibrato and arpeggio and melody should be smooth. In Bruce Lee's words, "be water, my friend" (although the original meaning is not that)
