Jigu and his two older brothers look like triplets, but IIRC they're all like 1 or 2 years apart - they're COMPLETELY IDENTICAL except for their hairstyles and personalities, and their mom is a smaller lady. The nephew looks like the boys, but he's like 5 years old.
The older brothers are a lot more extroverted than him irl, and the oldest seems to be the most "obedient" and has shorter hair than either son we've seen so far in the translated versions.
