 Two months later, this is his official June 5:  report to the Education Ministry and the National Central Library  .

Partial quote: 
"After 2 months of negotiations, we got 40 crates on June 1.
Planned to ship 18,000 volumes (about 255,000 books) on General Zhu's trip.
But the airplane was too small.
Humble apologies.
Beyond this first batch, I have required the Japanese to complete the detailed inventory list, the packaging and return all by the end of this month.
Probably can be achieved."
