The celebrated neolithic culture of Hemudu is known to have inhabited Yuyao, 100 km (62 mi) north-east of Hangzhou, as far back as seven thousand years ago.[11] It was during this time that rice was first cultivated in southeast China.[12] Excavations have established that the jade-carving Liangzhu culture (named for its type site just northwest of Hangzhou) inhabited the area immediately around the present city around five thousand years ago.[13] The first of Hangzhou's present neighborhoods to appear in written records was Yuhang, which probably preserves an old Baiyue name.[14]
