The reigning World and European champions Spain were made to work for their narrow win over the Chinese with David Silva scoring the winner six minutes from the end.
It could have been much more embarrassing for Spain had Zheng not missed two good chances to put the underdogs in the lead during the first half.
Despite the result - and his failure to convert his own chances - Zheng believes the friendly was a good learning opportunity for his team-mates.
"It's a pleasure to be able to play against the best players in the world, it's an opportunity to learn from them", Zheng told reporters.
Chinese striker Yu Dabao went even further by proclaiming Barcelona as the best team in the world and that their star players such as Xavi and Andres Iniesta will be vital for Spain's chances of retaining their title at this month's Euro 2012 tournament.
"Barca are the best team in the world, the best players in the world play there," he said.
"The Azulgrana players are very important to Spain's national team. Each one of them have special characteristics."
The European begin the defence of their title against Italy on Saturday.
