Late last year, Chow Sang Sang released a new wedding band collection called Promessa. Chow Sang Sang’s spokesperson and Taiwanese singer @林宥嘉 collaborated on multiple levels for the collection’s release. @林宥嘉 produced the theme song 《少女》for the brand’s launch event and stared in a promotional video. He also made an appearance at Chow Sang Sang’s Chengdu store to help with a new couple’s proposal. @临界十缨, @ 金旺猴哥Suye, @吕颖lvy and other KOLs also promoted the wedding band collection. The campaign’s Weibo hashtag #童心开始同心永结# tracked over 66M impressions.
