Ma Touqin is very difficult. The bow hair of erhu is two strings, which is easy to control. However, Ma Touqin's bows are separated, which makes it difficult for beginners to carry them. Moreover, many of Ma Touqin's songs are very fast, and the distance between bass positions is very large. If your hands are small, it is especially difficult to practice. Don't ask me how I know. I learned Ma Touqin first, and then I got in touch with the erhu, which was really much easier than the Matouqin.
