Authenticity. For example, in If You Are the One, the former female guests Ao Ming and Yang Lei (as if by this name) succeeded in holding hands and have developed very well so far. Ao Ming is not like many female guests who come to the show to hype themselves or choose bachelors. She is real and not so vain. She holds hands when she meets the right person. It's simple. Whether they can go to the end in the future has nothing to do with if you are the one.
Besides, there is never right or wrong in emotional affairs, and the seemingly absurd way of getting to know each other does not prevent two people from getting along and falling in love in the future. Sincerity is the key. In addition, if you are the one, it is also desirable. For example, Le Jia's analysis of the needs, personalities and matching degree of both parties is very useful.
