In what episode was Mulan dancing on the grassland in Hou Mengyao's version of the Mulan saga?

I've watched all 48 episodes, and I didn't even see the part where Mulan dances on the grassland in a pink dress, what a shame. That pink dress is what Mulan wore after she resigned from Pingcheng and went back to Wufeng Valley, I thought Duolun was going to take Mulan to the grassland to see the flowers at this point, and then Mulan improvised the dance, but it turned out not to be either.
