Which district is Shanghai Pioneer Company in?

There are two pioneers in Shanghai, one in Jiading Jiangqiao (Shanghai Pioneer Electroacoustic Equipment-SPS for short) and the other in Fengxian (Pioneer Hi-Tech-PSG for short). I don't know which one you are talking about.

Jiangqiao is a subsidiary invested by Japanese Pioneer in China, which mainly produces speakers for cars and mobile phones, and also produces semi-finished DVD products in cars and sells them to Fengxian Pioneer.

Fengxian, one grade higher than Jiangqiao, is a subsidiary invested by Japanese Pioneer Co., Ltd. in China. It mainly produces DVD products for automobiles, which are sold to Japan Co., Ltd. and then sold to customers by Japan Co., Ltd. China is just one of his production bases, and his profits are mainly earned by the Japanese head office. Just make sure she doesn't lose money.
