Shangguan and cuug are both regular training institutions in Oracle Bone Inscriptions, but the training fee of cuug is more expensive than Shangguan. Both companies have certain cooperative relations with some companies, and some old classmates recommend new students for employment, but only if you have certain knowledge as the foundation, and you can't study hard just because you can recommend jobs. I graduated from the official for one year, and my work was recommended by my old classmates.
