Do I need to apply for a Beijing permit to take the Beijing-Qinhuangdao Expressway from Yanjiao to Qinhuangdao?

Need. The Beijing Pass refers to the temporary pass for foreign motor vehicles without Beijing license to enter individual sections inside and outside the Sixth Ring Road in Beijing. Beijing-Qinhuangdao Expressway is a parallel line of Beijing-Harbin Expressway, starting from Tongzhou Beijing Sixth Ring Road in the west and reaching Qinhuangdao in the east. The passing section is within the Sixth Ring Road in Beijing, and you need to apply for a Beijing Pass.
