There is no direct bus from Guiyang Baiyun Park to Qingzhen No.1 Middle School, so you can choose to transfer to the bus. The following is a possible transmission scheme:

1. You can take bus No.236, No.251,No.252 and No.703 from Baiyun Park to Guiyang North Station.

2. After arriving at Guiyang North Station, you can transfer to Guanshan No.8 bus and go directly to Qingzhen No.1 Middle School.

However, the departure time of Guanshan 8 may be relatively fixed. The first bus may be around 7 o'clock in the morning and the last bus may be around 7 o'clock in the evening. So if you want to take the Guanshan No.8 bus, you need to arrange the time reasonably.

In addition, you can also choose to take a taxi from Baiyun Park or drive to Qingzhen No.1 Middle School, which takes about 40 minutes.
