Welcome, Archie!
Like Chinese infantry, Chinese artillery may be placed in any Chinese territory that China controls. Restricting their placement further would be too limiting.
Can the Chinese fighter fly out to sea to attack Japanese ships, and return to land in a Chinese territory (or Burma) or is it restricted to fighting only on land?
Thanks in advance.
It may not leave China, even temporarily.
@Dylan:

Even Kwangtaung?
Good question: can the ftr attack Burma or Kwangtung along with inf?
Yes, it may enter any territory that Chinese units may legally enter.
