Zengcheng is under the jurisdiction of Guangzhou, but it is not in the downtown area of Guangzhou, so it is not restricted by the management measures of "opening four and stopping four". However, it should be noted that if you drive into Zengcheng and violate traffic rules or laws and regulations, you may be punished accordingly.
Please note that the above information is for reference only. If you need to know more about Guangzhou's traffic rules and management measures, it is recommended to consult the local traffic management department or relevant official institutions.
