I really loved watching this show. In fact, I couldn't stop watching it! It's possibly (probably) one of the best shows of the year. With a raw storyline, amazingly complex characters, and competent production, this show is a good option for a mature and gut-wrenching experience.
Throughout the watching experience of this show, I noticed a lot of viewers were upset by characters not being easily categorized as good or bad, or judging characters too harshly, or just being upset that the romances were not cute. So just upfront, let me tell you. This is not your next Love is Sweet or Begin Again, or even Go Ahead (though that show is pretty close, content-wise). This show is raw. It's like an open wound. It goes for realism and it exposes the characters' faults on purpose. Actions have consequences in this show and everyone is a bit more complicated than meets the eye. I could write pages on character studies alone but this is a show review, so I'll stop!

You should watch this show if you like:
1. Mature stories. No black and white morality to be found here or cutesy characters whose bad decisions only lead to quirky shenanigans. Nope. You make a bad mistake here, you go DOWN!
2. Good acting
3. Later 20th-century history
4. Family dramas
5. Generational stories

Summary: The show follows the Qiao children as they struggle to survive in their father's home after their mother dies in childbirth. Yi Cheng, the eldest, makes a silent vow to never lose his dignity no matter what he faces in life. He struggles to raise his neglected siblings, keep them fed and in school while also following his own ambitions of raising himself out of his bad situation through education, all while maintaining his pride. As the story progresses and their lives get complicated by mistakes and tragedies, the siblings stay close together like the threads of a knitted sweater!

Plot: The plot is simple. It's life. It starts in 1977 and ends in 2005 and the show is committed to historical accuracy but other than that it shows the characters, their love life, their triumphs and failures with little judgment. You will hate some decisions and you'll love others. It's chaotic and illogical, the way that real life is. In real life, sometimes people make bad decisions and they commit to them longer than it makes sense to do so. It's the same in this show. I personally found everything in the story tolerable and nothing made me so angry as to make me want to stop watching. Everything flowed naturally. Nothing was dragged out and nothing was wrapped too fast. The pace was great and it helped to keep the viewer interested. Each episode is packed with one event after another to the point that missing one episode might lead to missing entire arcs!

Acting: Perfect. All across the board, everyone was amazing. Special shout out to Liu Jun who played their father. His character was a jerk but he played him so well that I was just so impressed by this veteran actor. Also, the young actors playing the Qiao kids in their childhood, especially the young actor for YiCheng, were amazing. Guo Zi Ming made me tear up more than any other character in the show. Kudos!

Music: I actually loved the music for this show. Especially the song called Wild Bird which I have been listening to on repeat since I watched the first episode. I can sing along now!

Production: It was near perfect. Gorgeous cinematography, meticulous location setting, attention to details, historically accurate objects but also experiences, symbolic lighting (happy homes colored with warm colors and unhappy ones with cold ones), (almost) perfect continuity. Most importantly, I think the production wasn't as expensive as it seemed and that it was just very well-budgeted.

Rewatch: I wouldn't say no. It was a very endearing watch and I particularly enjoyed certain parts that I would love to watch again.

Negatives: Characters make bad decisions a lot but I thought they made sense in context. While bad decisions, they still made sense for the characters. It's a bit hard to keep track of the passage of time. It's probably easier for Chinese people to figure them out because the show touches on important historical events but even so, there were certain points where time moved in loops (as it so often does in cdramas!) and it was a bit confusing but it didn't harm the show. It was just surprising to learn how much time had passed, once we did get a date. Some scenes were censored and there is some propaganda in the show. The censored parts do not redact from the quality but they do raise questions of "what if"s. The propaganda is light and harmless for the most part. One or two subplots lead nowhere in particular but given how packed the show is, it's fine. Qiqi gets WAY less screen time than everyone else. Not sure if it was a good thing or not because what we got from him was so sad and upsetting that I wish we hadn't had that either!

Overall: Highly recommended. I don't usually enjoy modern cdramas. This show stands out with its near-perfect everything.
