Dung,
it looks like Angular leaf spot, caused by Pseudomonas syringae pv. lachrymans.
Look at http://mtvernon.wsu.edu/path_team/cuc...

But, you must isolate the pathogen to be sure. The pathogen can be transmitted by infected seeds, by rain, etc. The pathogen will stay in infected plant debris until they will be completely decomposed. Copper-based fungicides or biocontrol agents can reduce the disease spreading.
