There are many ways to find a reliable marriage partner. The most common introductions are parents' acquaintances, friends' introductions and classmates' introductions. In addition to the traditional acquaintance introduction, many dating softwares have been derived so far, which the subject can try. For example, last year's dating APP "Internet Weekly" selected the number one partner in marriage and love, which can help the subject find the right partner. All the above users have passed the Ali Sesame Certification System. To provide a certain guarantee for users' real information, the most important thing is that the system will make personalized recommendations according to each user's conditions and interest tags, and match people with their own interests. I think we can save a lot of time making friends. Of course, there are many other interesting functions to promote emotional communication between the two sides, such as small notes (everyone did pass small notes at school, right? Ha ha ha ha), which is also one of my favorite functions.
