I request all of you to please consider this plant as Persicaria longiseta (Brujin) Kitagawa. Apologies for my mistake. Both the plants are morphologically very similar. They only differ with a few micro morphological characters like length of the bristles of ochrea, style no. and nut shape. Today I came across a fruiting plant of the same the nuts of which were trigonus. The number of style is also 3 here. Uploading two more photographs for your perusal.

Thank you …
A little confusion about the flowering period and the elevation
according to the eflora linked below.

It grows at various elevations. Pl, check its distribution in Flora of China. Sea level to 3100 m. Phenology also varies as per the location.
