Furniture is composed of four factors: material, structure, appearance
and function. Among them, function is the leader and the driving force
for the development of furniture; structure is the backbone and the
basis for achieving function. These four factors are interrelated and
restrict each other. Because furniture is designed and manufactured to
meet people's certain material needs and usage purposes, furniture also
has factors in terms of materials and appearance. Furniture mostly
refers to large items such as wardrobes, tables, beds, sofas and so on.
Chapter 18 of Liu Qing's "Bronze Wall and Iron Wall": "A guard with two
pieces of furniture carrying a box gun and a carbine came up." Household
appliances refer to woodware, including cooking utensils. It is an
appliance with functions of sitting, lying, leaning, storing, and
spacing used in human daily life and social activities.
