The Bundelsiga giants continued their pre-season preparations with a routine win against their Chinese opponents, who failed to make any impression on the match
A fortuitous own-goal gave the Bavarians an early lead, and they were in a commanding position at half-time thanks to further strikes from Arjen Robben and Claudio Pizarro.
In the second half, the Germans were equally dominant, and had the luxury of squandering a number of opportunities before Thomas Muller, Mario Mandzukic and Mario Gomez completed the rout.
Fewer than 10 minutes were on the clock when Robben made his first impact on the match. The Dutchman skipped through the Guoan defence, and the pulled the ball back to Pizarro.
The former Werder Bremen striker's shot bounced off the inside of the post, and as Wang Changqing tried to hack the ball off the line, he miscued it into his own goal.
Seconds later, it was two. This time, Jerome Boateng was the Roten star to gallop down the right wing, and the Germany full-back swung a fantastic cross towards the far post which Robben gleefully headed into the bottom corner.
The game was in danger of turning into a massacre, and were it not for some wasteful Bavarian finishing, Jupp Heynckes' side could have hit double figures by the break.
A smart reaction save from Yang Zhi prevented another embarrassing own goal, before an acrobatic scissor kick from Xherdan Shaqiri flew over the bar.
Franck Ribery attempted to walk the ball into the net, but took once touch too many, allowing Zhi to come off his line and claim the ball at the Frenchman's feet.
Robben motored down the left once more, pulled the ball back expertly for Toni Kroos, who forced an excellent save with a powerful strike. The resulting corner made its way to the former Leverkusen loanee, but he could only drive it well over the bar.
A third goal finally arrived on the stroke of the break. This time, it was Franck Ribery who made a break down the flanks, cut inside and crossed the ball to Pizarro who nodded home.
Shaqiri had time to squander one more chance before the interval, but in truth, it mattered little. Bayern were in complete control, and barely had to get out of first gear.
An early break from the hosts looked to have promise, but when Bayern had scrambled the ball away, normal service soon resumed.
Mandzukic came agonisingly close to making it 4-0, but saw his header bounce back off the woodwork, before Gomez blazed over an easy opportunity after being set up by Mitchell Weiser.
The fourth goal finally arrived when Gomez bounded clear of his marker, pulled the ball back to Muller, who was left with a simple tap in from a matter of yards.
Muller soon turned provider, racing clear of the defence in a similar way to Gomez, and finding Mandzukic, who coolly slotted home from the edge of the box.
Gomez finally had his goal with a little under 10 minutes remaining when he nodded home a pinpoint cross from Shaqiri, and Bayern's work was done. Heynckes' side had earned a convincing victory against an opponent who barely had the ball, and did so without having to exert themselves.
Bayern continue their pre-season preparations with a clash against fellow Bundelsiga outfit Wolfsburg on Thursday.
