Super god damn detailed map. Don't know why I did it.
Presuppositions:
1) moving 1 division from the reserves or cadre forces from other regions by rail = 1 day.
2) moving 1 division from the reserves inside the region by rail and deploying it = 1 day.
3) Chinese divisions are 15 000, not 20 000 as the latter is an obvious cop-out attempt by Beowulf to strong-arm allied forces (even if they are, that's another 60 000 to his forces for a total of 930 000 men, and thus for a rough parity with the USSR forces in the area in a strategic sense; in a tactical sense the USSR still has extreme superiority)
4) division defence width = ~20 km (standard post-WWI plans)
5) divisions spread to 100 km in mountains
6) fortress divisions concentrate to 20 km from 100 km when attack imminent (else the situation would be too bad for Beowulf)
7) Manchuria: 3 cadre fortress and 3 cadre infantry divisions man the 500 km long border with Mongolia - 1 Reserve corps is also in that territory. The rest man the 1000 km wide border with Russia. 3 Mountain infantry divisions are in the North as Beowulf specified.

Railway brigades and railway artillery brigades (500 man each) cannot further follow forces due to lack of railway links with Manchuria, hence 1500 men (3 br) left manning breach in the South and 1000 men (2 br) left manning breach in the North.
9) Forces mobilize at large mob. centers not in empty space; 3 of my reserve Corps (Chita) and 3 of Beowulf's corps are mobilized beyond the immediate vinicity of hostilities. 7 of my Res Corps mobilize at inhabited towns and villages in the area, including Mogocha, Nerchinsk, Sretensk, Priargunsk, Zabaikalsk, etc. 6 of Beowulf's Res Corps mobilize at Gulian, and other inhabited points and railway junctions at line Yi.
10) There are no 3000 km long total track laid, purely military railways running right along the border, because no nation has had such feats made even with their defence lines, in the 1930s. There are railways which extend to larger fortified regions along the border.
All mobilization calculations are on the picture.
