Personally, the construction speed after the Spring Festival is not as fast as that at the beginning of the year, and the obvious change is only that a section of side wall is installed in the front. Perhaps they put their energy into improving the internal equipment installation of the part that has been completed at present.
I think this is normal, after they added each module block they will have to work inside the connected modules to install piping, cables, welding, and fixture and fittings like furniture, machinery, equipment, internal painting or coating etc.
I also believe interior works take longer time to complete than the basic module blocks, sometimes we don't see any progress externally like it take a long time to add a new module.
We have also observed that modules were placed on the dock yard for a long time before they hoist it to join the hull in progress.
But naturally we are more excited to see external changes than the un-observable progress inside the hull.
