You can’t be friends with people you have zero interest in what they say and they will know you have zero interest and in turn have zero interest in you
yep, from each job I had in the past I stayed friends with 2 or 3 people after leaving, from dozens I worked with in each place. it’s nice to have friendly co workers, but they are just that… you choose your friends.
Generally speaking you will find the people further south to be more genuinely interested in you and thus, friendlier - as in TaiZhong, TaiNan… So take what others say about YOU with a grain of salt
