Mine vary both in response and situations as to how much contact they like with strangers. Heidi is quite nervy and doesnt really like being stroked, although if she is at home she will be climbing on someones lap within half an hour of meeting them.
Hannah, my Chiweenie, is a lovely calm girl who enjoys meeting people. In fact if she ever disappears whilst down the park you just have to look for the nearest person and she will be climbing on them and rifling through their bags!LOL
Adam is my super friendly Chi.

He is a total social butterfly and will pull towards every person when walking whilst wagging his tail and trying to get fuss. Ive had several people tell me they never realised chi's could be so friendly after meeting him.
All 3 have the same preferences for people though. They arent that keen on men and the elderly but like women and adore kids and babies. All mine were socialized the same but genetics will still affect their behaviour. Heidi is just a more nervous Chi in general and I dont think she will ever be as comfortable as the other 2.
(just today we meet a group of little girls who were stroking the dogs and getting kisses. Adam was in heaven when one of them picked him up for a proper cuddleLOL)
