What episode is the alternate punishment after Wei Zi becomes a princess?

In episode 60, Erkang rushes to Wei Zi's bedroom to reaffirm his loyalty. Wei Zi became sensitive to moral standards because the Queen Mother belittled her mother and asked him to go out. Sunny came to show that she would never marry Erkang. Wei Zi Swallow, dressed as a eunuch, went out with three guards on a non-palace day. Everyone thought it was not feasible to persuade the emperor to give up Han Xiang, so they put forward a "plan" to smuggle Han Xiang out of the palace at an appropriate time. Everyone drank to drown their sorrows, and the two girls went home drunk and were caught by the queen mother who had already been in Shu Fangzhai. The Queen Mother punished everyone, and Wei Zi and others were beaten.
