The written Chinese language played a critical role in shaping the emergence of a distinctively East Asian cultural zone. The development of writing in Bronze Age China is thus fundamental to both Chinese and East Asian civilization more broadly. Although tantalizing examples of markings that seem to resemble writing have been discovered from earlier periods, the first unmistakable examples of written language in China appear on the 'oracle bones' that were used for divination at the late Shang court. During the fourth and early fifth centuries, Xianbei bands in the northeast established a series of dynasties in the area of southwestern Manchuria and northeastern China proper. In the early sixth century, there was reportedly a steady flow of merchants from the remote west arriving in the Northern Wei dynasty capital at Luoyang, in north-central China. Buddhism was then introduced to Paekche by a Central Asian monk, Malananda, coming from Southern dynasty China in 384.
