In China, an online dating startup has launched, working on the principle of "marry or refund" - with a refund of the subscription fee if the user does not marry within three years. The annual subscription costs 21,000 yuan (about 24.5 thousand rubles). Liangpei AI only selects one potential partner at a time. To meet another person, you must complete an acquaintance first. When registering, you must state your real name, upload a photo and confirm the absence of marriage. New users go through a 20-minute AI interview. Based on answers about family, education, work, interests, character and preferences, the system creates a detailed profile for matching. Tag: MID.
