The launch of 'Dajia Hui Xuan' by Huize in partnership with Dajia Annuity Insurance is likely to have a positive impact on Huize's stock in the short term. The introduction of a new product could expand Huize's product offerings and potentially increase its customer base, which may lead to increased revenue. However, the actual impact will depend on the market's reception of the new product and the effectiveness of the partnership.
