It's only a matter of Electronic signature of approval .. a typical process for today completion .!!
And before 10 minutes the same employee informed me that Certificates of transfer of property are approved and sent to my Tax e-box. .. I have seen them ..!!

My idea is that the timing factor comes from Hai "holding" Yin.
Sure, if Shen day comes, Yin will be clashed and Hai will release it.
Logically, in Si day that may happen as well, although not sure.
However, if the Hai month turns to Zi month, again there will be no Hai holding Yin. So it would happen on the first few days of the new month.
