I am also waiting to watch these TV soups especially 我家公主. However, it is too early to tell the "on air" day. Only 終極一家 have finished filming but seems that it is now in final production before it can be on air.
Yes, it is on air in 八大 so far as I know.
Let's us wait patiently. I think we will easily know if the on air days is announced. Let see the blog of the 飛輪海 artiste and you will know.
