There are three ways to reserve seats in Henan University, namely, choosing a landline, website reservation and WeChat reservation. The reserved seats must be signed in the library before use. Seats reserved on-site through the library landline will be automatically signed in after the seat selection is completed. Readers who reserve seats on the same day through the webpage and WeChat need to sign in at the library within 30 minutes after the reservation is successful, and cannot cancel after the reservation is successful.
