There are many modes of drainage now, and celebrities teach you to do self-media drainage. I also do pioneering work and training for beauty salons. Experience tells me that, first, you should read the questionnaire of plastic surgery customers, then analyze your data and be a pioneer. General customers are divided into online and offline. Needless to say, online has its own advantages. Offline still needs to be promoted in several key places. For example: school, early education, English school, bath club! Plastic surgery is divided into 28-35 years old and 45-55 years old.
