The new remote-controlled submarine took Zhang three months to build and has undergone checks
After being laid off in 2008, Zhang decided to make his own submarines, reports the People's Daily Online.
He completed his first in 2012 and has since opened a studio in a warehouse to make the vessels.
The mini submarine had enough for two people and could dive for up to 98 feet.
It can travel at 20km (10.8 nautical miles) an hour for ten hours and is equipped with oxygen tanks and video cameras.
Zhang says he's spent around three million yuan (£362,00) making three submarines.
He had intended to make a manned research machine but due to security risks and checks, he abandoned the procedure and turned to making a remote-controlled submarine.
The new wireless remote-controlled submarine took Zhang three months to build and has undergone checks and trials.
Photos show the submarine being tested in waters and Zhang Wuyi posing with his invention.
