Happy Lunar New Year!
Where I grew up, in Malaysia and Singapore, this festival (along with Hari Raya Puasa (the Muslim Eidl), Diwali and Christmas) were open-door celebrations, with neighbors and friends dropping in and out of the celebrants’ homes to wish them well and to partake of the festive goodies. They would mostly be invited, although it would be perfectly normal also to drop in unannounced (to avoid horrified looks, this helps if you know the person 😉 ).
My late Granddad’s best friend, Uncle Guan (which was actually his first name), was Peranakan Chinese. He was a descendant of late 15th and 16th century immigrants to the Indonesian islands, who adopted some of the local customs and style of dress, and developed their own hybrid of Nyonya or Baba Chinese cuisine.
He also might have been a perfect character for an Asian version of the TV drama, Big Love (albeit a more genteel, non-violent one) .
