Lee won all eight 500m races scheduled ahead of the trip to Germany however, with the Korean not competing, Wang took it upon herself to claim victory.
She clocked 38.07seconds for victory with Dutch skater Thijsje Oenema finishing second 0.27 behind with home hope Jenny Wolf just another 0.05 further adrift in third.
Lee is still the champion elect though with Wolf trailing the Korean by 249 points with just three races, including one more in Erfurt, left this season.
Meanwhile Bob de Jong recorded an extremely fast 10,000m time as he and Dutch teammate Jorrit Bergsma destroyed the field in Germany.
De Jong clocked 12:53.56minutes with Bergsma 1.80 behind in second before Korean Lee Seung-Hoon 26.28 behind the Dutch winner in total.
Just 20 points now separate Bergsma in the lead of the overall joint 5000m-10,000m World Cup standings from de Jong in second.
And in the ladies' 5000m Martina Sablikova claimed her second win over the distance this season and leads the overall standings for the combined 3000m-5000m.
Sablikova clocked 7:01.33 for victory with German hopes of a win dashed again as Stephanie Beckert finished second 1.51 behind and Claudia Pechstein over three seconds back in third.
