anybody knows bus route that can take me from Guangzhou Lingnan Institute to Baiyun Mountain?

I wonder whether you refer to the Guangdong Lingnan Institute of Technology. If so, you can walk to Kexue Dadaokou bus stop to take bus line B4 and get off at BRT Huajing New Town. Then transfer to bus line B16 and get off at Yuntai Garden General Station. After that, you can easily walk to the scenic area.
