Does anyone know the correct order of reading CLAMP?

like the order of the anime and movies?
if so-
Cardcaptor Sakura, cardcaptor Sakura (Hong Kong), cardcaptor Sakura (the sealed card), cardcaptor Sakura clear card.

Imagine if we include TRC and xxxHolic in too...

There is no particular order, however if you want to read xxxHOLiC you need to read Tsubasa Chronicles, and their order is:
(You can start with either one)
Cardcaptor sakura ( can be read independently but eventually clear card will cross over with holic and trc)
Xxxholic
Tsubasa Reservoir Chronicles
Xxxholic rei
Tsubasa Reservoir world Chronicles
Cardcaptor sakura clear card
Of you want for the other series it gets confusing but if you want I can write them up for you but it will take kind of a long time since characters crossover, and some happen in the same world but in different timelines
