China - 5 factories
at Taku:
1 Type 1 slip
4 Type 0 slips
1 Type 1 drydock
2 Type 0 drydocks
at Shanghai:
2 Type 1 slips
2 Type 0 slips
1 Type 2 drydock
1 Type 1 drydock
at Zhanjiang:
1 Type 1 slip
2 Type 0 slips
1 Type 1 drydock


That's, what i find for China.

The following changes simulate the activities of the Chinese government in the last decades. The industry was a little modernized as well as the ships from the past century against new buildings were changed.

I set 5 points for modernization of the infrastructure.

Minor Changes of the infrastructure:
One Typ1 Slip in Shanghai changed in Typ2
Two Typ0 Slip in Taku changed in Typ1
New Two Typ0 Slip build in Taku

I hope the changes get your agreement. It is naturally only a suggestion.
