This is a vintage, 3rd quarter 20th century original framed painting in a modest 18" x 14" size. The depiction of a rickshaw driver and stone buildings with steps along with the stylized depiction of the figures wearing hats is more likely a scene from Vietnam than China. This does appear to be signed at lower right, however a clear, in-focus close-up of the signature was not included. These were generally made for the tourist trade as a decorative wall art souvenir. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
