How to take a bus to Dongying Shida Shenghua Chemical? Ask for an urgent answer

Shida Shenghua has two factories. The old factory is in the north gate of Petroleum University, and you can get there by bus No.7 from the bus terminal. The new factory is in the northern suburb of the No.8 branch factory, and there is no bus. Before and after the shift change of Shida Shenghua, there is a company shuttle bus from the north gate of Petroleum University to the new factory. Foreigners can also take the shuttle bus, but I don't think you will go.
