To celebrate the Chinese new year, Hyatt has a promotion where they are giving out 100 Free Hyatt Gold Passport points.
“Officially” this promotion is targeted, though from personal experience, the points are posting even when not targeted, but just beware that there is a slight chance the points won’t post.
Also, Now that Hyatt has started expiring points for non-activity, with this promo, the 100 points constitutes activity and will thus extend the life of all of your Hyatt points for another 24 months.
If you do not yet have a Hyatt gold passport number, you may apply for one here.
