Yes, now Qiao Yu was entirely immersed in mathematics, intensely focused.

Qiao Yu got up early, washed up, and went to the cafeteria to have breakfast. He then took his prepared paper, completed the registration, and handled the check-in process.

It's always like this, once Qiao Yu has a clear goal, both his concentration and personal energy seem to be even more vigorous.
This can probably be described as a highly motivated attitude.
