It's not so much about reconciliation between a divorced couple, but A Beautiful Life is rather similar in their exploration of relationships. The protagonists in both films are faced with problems that require love, patience and pure tenacity to be able to endure and overcome and that's probably what draws common ground between the two. Without giving away too much however, I guess you could say that A Beautiful life is also about reconciliation between a couple as there is at some point, a bump in their relationship.
Both productions show life and love of immigrants in either mainland China (Beautiful Life) or Hong Kong (Comrades). First half of A Beautiful Life is quite similar to Comrades: Almost a Love Story as it features not-quite-romance between a naive and warm-hearted male lead and business savvy female leads.
