Thanks, Ah-bin, for your reply!

Mandarin has diverged more from its ancestral language than Hokkien has, that's all. if Mandarin had actually developed from Hokkien, then you could say that it was more ancient, but that is not how Hokkien developed.
Agree. I think no one would say that Mandarin had developed from Hokkien, but most probably they mean that Hokkien preserves more "ancient" features. But even this is debatable, as you have explained.
It is more accurate to say, I think, that Hokkien preserves more features of Middle Chinese than other varieties but even this is debatable since it has merged many of the old initials and (in the Amoy variety) no longer has a distinct 陰上 and 陽上 like Cantonese does.
Agree also. I think many Sinitic languages preserve certain aspects of Ancient/Old/Middle (etc) Chinese. Hokkien preserves ancient terms like 有身 (ūsin) for "pregnant" and pronunciation of 滑 (kùt) is still very similar to 骨 (kut), but has lost many of old initials and some of the tones. This should be true for many other Sinitic languages, e.g. Cantonese preserves the tones. Is it more accurate to say so?
The tree I have in 臺灣的客家話 actually puts the Wu dialects first, since they preserve the most initial sounds. They have simplified all entering tone endings to a glottal stop, but then again, so did Hokkien, until it began to borrow words from the Chinese of the T'ang capital.
Wow, that's enlightening! So without borrowing words (pronunciations) from T'ang capital et al, Hokkien would have been much more similar to Wu! Any particular reasons why Wu could resist such borrowings?
Then, what do we count as the stability of sounds over time? Hokkien has lost the voicing in the initial [p] in 飯, where Soochow has kept the voicing (old feature) but made it a fricative [vE]. In Hokkien the sound became the same as that of 分 [pun] when the initials were distinct in Old Chinese. They are still distinct in Soochow (分 has an [f] initial). So do we count the distinction in Soochow as the older feature or the lack of a fricative in Hokkien as the older feature?
That makes linguistics interesting!
