There are indeed many teachers now, and some have only taught the basics for many years. As an old balloon man for many years, the balloon party industry belongs to a relatively fashionable industry. If you don't improve your aesthetics and color matching can't keep up with the current fashion trend, you will be gradually eliminated by the industry. Therefore, no matter what industry you are engaged in, you must keep learning to develop better. Personally, I think the teaching quality and curriculum arrangement of Heze Dabai Balloon Party Training Center are the most comprehensive and reasonable in China.
