"有你才幸福" seems to be a Chinese drama or movie. However, I can't provide a direct link or streaming source as copyright laws and regional licensing agreements restrict sharing that kind of media content. You can try looking for legal streaming platforms that have licensed this show/movie in your region, such as iQIYI, Tencent Video, or Youku if you're in China. For other regions, check local legal streaming services or the official website of the production company. Always ensure you watch content through legal means to support creators and rights holders.
