The lecture published on Guo Tu's website was held at 4 17, East District, South District. You don't need to get a ticket in advance, just have an ID card, and you usually enter the venue half an hour in advance. Some lectures on Jinwen Street may need to apply for electronic tickets, which are usually indicated on the website.

There is also a public lecture held by Guo Tu Concert Hall, which is the kind of Jiayantang, but you need to make an appointment one week in advance. Most of these are art lectures. For example, Jiang Kun will be invited to give a speech on June 10.

According to my personal experience, it is worthwhile to attend the 4 17 lecture in Guo Tu East District. For example, last week's "Iranian nuclear issue" was very good. You don't need to buy a ticket in advance. Just go in when the door opens at 9: 00. Don't be late. The lecture usually begins at 9: 30.
