suppose chinese language education is a production, and any of the successful products has a life cycle; however, the question is now hanging over us: how long is long? if we divide this life cycle of chinese language education into 3 stages that are beginning, growing and maturity, what stage are we at? but anyways, in the beginning stage, it's growing fast with an upward curve. as soon as it's reached the growing stage, it's still growing but with a downward curve until arriving the peak. and we call the the rest of the part as a maturity stage. it will be depressing and gradually out of the market.
