Just turn on the wireless network, find hit WLAN- Xiaowai, and then click the browser, and a page will pop up to prompt you to enter the account and password of the campus network of Harbin Institute of Technology (note that the account here refers to the number running in the network center of Harbin Institute of Technology, not Netcom or other online accounts), or find hit WLAN- Xiaowai without an account, just on the campus network of Harbin Institute of Technology. I hope it works for you ~
