As the prehistoric Beifudi site is in northern China where the climate is drier than in the south, it is likely that this culture cultivated millet although no direct evidence of cultivation has been found.
Sebagai situs Beifudi prasejarah berada di Cina utara di mana iklim lebih kering daripada di selatan, kemungkinan bahwa budaya ini dibudidayakan milet meskipun tidak ada bukti langsung budidaya telah ditemukan.
