It should not be deliberate, it should be natural and cordial, and it should not give people the impression that it is very artificial and deliberately close to ta. This kind of thing really goes hand in hand. Can't be forced. People can't win everyone's love, nor can they make many intimate friends. Only one or two bosom friends. Most of them are casual acquaintances, or friends who have to be together because of some connection. Smile at people at ordinary times, whether you know them or not, others will think you look easy to get along with and naturally want to know you. Be polite, easy-going, humorous and charming, but be careful not to be grandiose, frivolous and rude. Be sure to be honest with others. You give your heart, and others will repay you with the same heart when they see it. Don't do unto others what you don't want done unto you.
