Like most of the conventional arts, Glove Puppetry is facing the same situation where there are no successors. Although they are still performing in many places, they are going to get old someday. They need to find people to pass it on.

If they want to enlarge the scale in development, they don't have enough time to do so. They are not young anymore. Moreover, there is no successor, so if they put more money in it, the risk of losing gets higher. If they want to maintain the way as it is, the problem of having no successors is not solved.
Thus, for now, all Mr. Wu can do is to do his best to perform and hope for the appearance of those that are willing to take over Peiguan Glove Puppetry and pass it on, making it flourish again.
