Man Zhiguo is checking in on his 70 prizefighters.
He's been raising and fighting crickets for over 40 years and some of his most valuable insects are worth around $1,500 U. S. dollars apiece.
Which could get expensive, because crickets have a lifespan of about only 100 days.
SOUNDBITE: Man Zhiguo, cricket collector, saying (Mandarin):
"I raise crickets as a hobby because I admire their positive spirit. They never admit defeat, they have a fighting spirit. So we all like them."
Not unlike boxers, these fighters are fed a high protein diet and are "trained" for competition.
And after the weigh-in it's time for the first matches.
The insects take a bit of coaxing, but they're soon locked in fierce battle.
Each team was allowed to have 35 crickets and after two days of battle, Man's insects won all their bouts - not enough for his team to take the trophy, but certainly something to chirp about.
