Is Beijing bus 867 going to operate in April (April 2nd specifically)?

The former no.867 Tourist Special Line from Dongzhimen Outer (Dongzhimenwai) to Mutianyu has been concelled. But you can take the normal no. 867 bus that departs at 10:00 and 12:00 and get off at Mutianyuhuandao. Then walk 3-5min to the ticket office of Mutianyu Great Wall.
