Which courier company in Changshu is cheaper?

If there are many things, use Dayun Express. I'm from Suzhou University, and the student union of the school organizes Dayun Express. It mainly charges by parcel. A large travel bag does not exceed ten yuan. You can buy a few big bags and pack them yourself. It's very cheap to deliver in the same city. I only know that it costs six yuan for Changshu Institute of Technology to go to Suzhou University.
