Wang, from China, became the first skater that wasn't Lee to win a World Cup race over 500m on Friday and she repeated the trick a day later in Germany for the distance double.
She went slower in 38.15seconds with 0.07 separating first and fourth as Russian Olga Fatkulina took second in a dead heat with Dutch skater Thijsje Oenema.
German Jenny Wolf was then just 0.01 further adrift in fourth and, with Lee absent, is now 189 points behind her in second in the overall World Cup standings for the 500m.
Meanwhile Smeekens is on the charge in the men's 500m taking his third successive victory of the season in 35.06 with Joji Kato second and Ronald Mulder third.
Smeekens leads Japanese skater Kato in the overall distance standings by 124 points while Dutch teammate Ireen Wust claimed a second straight win in the ladies' 1500m.
She comfortably led home a Dutch one-two-three beating Diane Valkenburg by 2.71 with a time of 1:55.61minutes while Marrit Leenstra was another 0.06 adrift in third.
American Brian Hansen denied another Dutch victory in the men's 1000m defeating Stefan Groothuis by 0.05 for his first World Cup win in the distance this season.
The result has little affect on the overall 1000m standings though with Kjeld Nuis, ninth in Erfurt, leading Hein Otterspeer, who was 11th, by just three points.
However the Dutch were back to winning ways in the men's team pursuit as they beat Korean by 0.12 while Poland were a clear third ahead of Russia.
