What was one reason that china lost the sino-japanese war?

If you mean the first one, corruption was one reason. The Chinese navy and military were incredibly corrupt (as was the government) -- funds meant to buy ships and ammunition were often embezzled by officers for other uses.
Pay in the army was low, morale was low, compared to the Japanese military which was also modernized but based on Western principles and proven tactics.

The  pan-african movement  was an "emotional, cultural, psychological and ideological  movement  that began among the  african  dispora in the western hemisphere, for a closer  purpose, so that  african  people could feel secure, attain political, economic as well as psychological power visa vis other races or world regions" .
