Every time in history for the enterprise technical update will bring new development opportunities , and even changes in the competitive landscape of the industry : such as: Lactic acid furnace with respect to firewood stoves, gas furnace appear relative to coal-fired stove, cooker appear on the gas stove and other appliances industry continues to reshuffle brought ; color TV vs. black and white TV , LCD TV , etc. with respect to a large number of ordinary CRT television manufacturers continue to bring new development opportunities.
