Examples would be the production of kaoliang wine, which begins with the planting of sorghum; the process of ceramics production, which begins with mining and carries through to the finished object; and the making of native candies, beginning with harvesting the peanuts. Transportation to see these industries is convenient because they are all concentrated within a 100-square-kilometer area of land.
譬如由種植高粱到生產出高粱酒的過程，由陶瓷廠採礦到製成各種陶瓷成品，由採收花生到敲製成貢糖……，這些產業都集中在百平方公里以內，不需花太多交通時間。
