Juniper bonsai has certain cold tolerance. But ... in winter, it is recommended to put it in a cold room or even bury it in an outdoor shelter from the wind and sun. Be careful not to water it too much.

It is better to trim and reshape in winter, and cut off redundant branches, branches with bad angles and other branches that affect the tree shape. For the branches that are too long, the core can be removed during the growth period to promote the emergence of new buds and make the branches dense.
