According to the discussion, some information is true, but you have not updated yet:
Citybus: #830
NWFB: the unknown x = 6; so the bus that printed the advertisement of Year of the Rat is DA96.
KMB: Does anyone know how many buses will have the advertisement? 1? 2? or 3?
P.S. Your i- and a-powers go to hell because you have not updated the information. If possible, make the correction.
