The laser marking machine developed by HGTECH can make a metal bookmark in less than a minute based on customized needs. "People only need to write words they like, and then the machine will put them on the bookmark," said a staff member from HGTECH.

The audience was also amazed by the Zidong Taichu multi-modal large model produced by the Wuhan AI Research Institute, which can write an essay in 50 seconds and paint a picture in five seconds.
