As with food supplies and clothing, the availability of housewares went through several stages.[1] Simple, inexpensive household items, like thermoses, cooking pans, and clocks were stocked in department stores and other retail outlets all over China from the 1950s on.[1] Relatively expensive consumer durables became available more gradually.[1] In the 1960s production and sales of bicycles, sewing machines, wristwatches, and transistor radios grew to the point that these items became common household possessions, followed in the late 1970s by television sets and cameras.[1] In the 1980s supplies of furniture and electrical appliances increased along with family incomes.[1] Household survey data indicated that by 1985 most urban families owned two bicycles, at least one sofa, a writing desk, a wardrobe, a sewing machine, an electric fan, a radio, and a television.[1] Virtually all urban adults owned wristwatches, half of all families had washing machines, 10 percent had refrigerators, and over 18 percent owned color televisions.[1] Rural households on average owned about half the number of consumer durables owned by urban dwellers.[1] Most farm families had 1 bicycle, about half had a radio, 43 percent owned a sewing machine, 12 percent had a television set, and about half the rural adults owned wristwatches.[1]
