Applying in person?

Hello, can anyone point me in the right direction for this issue. I'm a passport holder of one of the following countries listed below. According to G3 Visas, I must appear in person to apply for a Chinese visa. Does this mean I cannot even hire a visa service? I want to confirm what g3 visa states, but I cannot find any info on any official Chinese visa website. Does anyone have experience with being a passport holder of these countries and had to apply in person? Thank you!
