You can buy books to teach yourself. At present, there are few professional exhibition design books, so you can search for "exhibition design of shops" on the Internet.

You can attend the training. There are China Fashion Designers Association Training Center in Beijing/Shanghai, Pan Am in Shenzhen and Dalian Institute of Light Industry in Dalian. These schools have longer courses. Short-term courses include Lianhe Times and China Institute courses, which are from Beijing.

You can also take the exhibition designer qualification examination organized by China Fashion Designers Association. It is more convenient to find a job with a certificate.

You can also start as an exhibition assistant, hoping to meet a master leader and learn from him.

Many methods are available, depending on your choice.
