Do You Need a Second Auspicious Date After the Dong Tu Ceremony for Renovation?
Feng Shui Guide: Auspicious Dates After Groundbreaking (Dong Tu) Explained"

Hello Mr Cecil, 1. After 动土 ceremony, do we need another auspicious date to kickstart the actual reno? 2. ID is thinking to start hacking in early Sep (after defect check), for the coin placement, do we need to select an auspicious date as well?

1. Most individuals generally lack the time to initiate a secondary process. However, nothing precludes someone from proceeding, as the relevant dates are already available. This individual may simply be among the rare few in Singapore to undertake this for an apartment.

2. As previously mentioned, the dates have been supplied, and most people complete this process only once. Nevertheless, if an individual has ample availability or is particularly cautious, they are entirely welcome to proceed again. It is merely a less common practice.

Candidly, the majority of my clients share a common sentiment, often questioning if such actions imply an excess of free time.

In reality, most clients maintain demanding schedules and lack the availability to engage in duplicate procedures; otherwise, they would inform me. Nevertheless, there are always a rare few who choose to proceed differently. Extra "ECA" is your personal CALL. This is Optional.
