Is tsubasa chronicles really the continuation of card captor sakura?

No, it's not the continuation. Tsubasa is a completely different story from CCS.

But yes, Tsubasa and CCS' stories are somehow linked.
The Sakura Kinomoto (Cardcaptor) meets with older Sakura (Tsubasa) in her dreams. Sakura Kinomoto gives her staff (The ngôi sao wand) to Sakura, saying that 'You know, everything will be all right'.
The staff ended up being a payment for Yuko later. But that's a whole different story.

As for the Syaoran in CCS, I don't think he made an appearance, though.

i don't know either ??

Its a different story with the same characters so...im pretty sure that its a different story and not a continuation.

The story can be really confusing to explain.. But no, Tsubasa is not a continuation of CardCaptor Sakura.

yes it is because bạn can see Sakura from Cardcaptors in it she is in the beginning with her Son which is Li syaoran named after his father from cardcaptors Now Li from CCS never appears in the hiển thị but in the manga he is mentioned Sakura from CCS is also hiển thị in both ova's in Tokyo when sakura (clone) goes to get the treasure she see's her and she is also seen in shunraiki after (clone) sakura get's taken when Fai is talking about how he knew sakura was a clone they are shown side bởi side hope this helps your câu hỏi

The stories overlap each other since they are in CLAMP universe.

No, Tsubasa Chronicles is not a continuation to Cardcaptor Sakura. CLAMP uses a literal device called a crossover. CLAMP uses the same characters from these two animes and shares them. The characters may be the same, but their plots are different. EX: Sakura Kinomoto from cardcaptors is a 4th grader at Tomoeda elementary. She collects clow cards. In Tsubasa Chronicles, she is the princess of clow country who loses her memories in a form of feathers.

Yes because in manga, shaoran is the son of sakura kinamoto with syoaran from cardcaptor sakura. Sakura from cardcaptor sakura can see the future of her so, she and his husband syaoron teach their son to be independant.syoaran also say that his father is better at cooking than his mother and he also have his parent picture in episode 1

It may be a story that infused parallel universe theory in it.
A physic theory referring to many possibilities that could happen in one person.
We maybe a princess hoặc someone else in other time hoặc place "partition" :)
