Is Tsubasa: Reservoir Chronicle continuing from cardcaptors?

Question

i don't get it because there have the same characters. answer the question and say WHY?

Answer 1

No.  The creator of both series', CLAMP, just reworked the some of the characters.  Although they have similar appearances and traits, they are  not the same characters.  They are more like AU (alternate universe) versions of each other.  Tsubasa was inspired by Cardcaptor Sakura.

They are two totally different stories.

Answer 2

though what you ask is right

but the same characters have nothing to do with this question at all

Yuko pointed out the definition in the initial:

you can see the same person in every different dimension

for example,the lead Sakura is the princess of Clow Country

as a foreigner, she is surely unrelated to Kinomoto in Japan country

there is only the same dimension to serch for the relation

in xxxHOLiC vol one,

Yuko mentioned that she knew well with the creator of Clow cards, Clow Reed

they also created Mokonas together

Feiwang Reed and Syaoran are also relatives of Reeds
