Picture taken in early March, east China (Zhejiang province). This tachinid fly has fiery-red hair on abdomen, scutellum and legs and looks somewhat like Tachina ardens in our gallery (https://diptera.i...o_id=11471) but some details are noticeably different, including the thorax coloration. Could it still belong to the same genus, that is, Tachina? Many thanks in advance.

Yes, this is a Tachina subg. Servillia.
There are many species in the eastern Palaearctic.

Wonderful! Thank you Theo very much for the confirmation and the sub-genus ID! I'll see what I can find in this Servilia direction.

Good news, the key in Flies of China says there are only three species of Tachina (Servillia) with dark calypters, and they have a dark body with reddish hair on the abdomen like your fly. Bad news, your fly is not any of those three species, all of which are found far to the west and also differ in some color or structural character.

The illustration of Tachina bombidiforma (Chao, 1987) shows proclinate orbitals, and although the sex is not specified it is paired with an illustration of male genitalia. T. furcipennis (Chao & Zhou, 1987) has light hair and pollen on the head. T. haemorrhoa (Mesnil, 1953) has a broader frons. If general appearance is reliable you have a cousin to these species. General appearance is not always reliable in Tachinidae.
