Dichorragia nesimachus
In 3 days ~20% in a week ~30%
Dichorragia nesimachus, the constable, is a species of nymphalid butterfly found in Asia. The genus was earlier considered to belong to the subfamily Cyrestinae and sometimes the Apaturinae, but is now considered as a sister of the genus Stibochiona in the subfamily Pseudergolinae. Several geographical forms with variations in colour are noted within the wide distribution range extending from India in the west to Japan in the east. In Vietnam, it is thought to show hill topping behaviour and is typically found in dense forest habitats. They may also be found mud puddling with other species.
A closely related species Dichorragia ninus is found in New Guinea and surrounding islands although some authors include it as a subspecies of D. nesimachus. D. n. nesimachus (Sikkim, Bhutan, Assam, Manipur - Indochina, South Yunnan) Wikipedia →

With luck
About 10% of wildlife watchers report a Constable sighting in Nanjing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 242nd most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Constable in Nanjing on a given day, against under 5% in October to July, the lowest months. That is one of Nanjing's wettest months, with about 160 mm of rain against 40 mm in December.
Yes
Of the 3 cities where we can rate Constable sightings, Nanjing has the highest daily chance: about 10%. Next come Taipei (Taiwan, under 5%) and Tokyo (Japan, under 5%).
Same family: Nymphalidae
The closest relatives of the Constable that you can see in Nanjing (family Nymphalidae, Brush-footed Butterflies) are Spotted Leopard Butterfly (about 20%), Blue Admiral (about 20%) and Asian Comma (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Constable is recorded against all the insects logged in Nanjing (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
