Help Particles go through the bucket

[TsaiHao]

Hi, I am using Obi Fluid in steamvr. I wanted to copy the bucket sample in my project and it worked fine in origin scale. But when I scale the bucket to (0.2, 0.2, 0.2), particles just went throgh the bucket. I changed particle material and resolution and not help. How can I solute this?
Best wishes!
