Hello, friend, this time it's harsh, of course it's not appropriate. When we face some sensitive issues, we need to treat them more rationally and objectively. The original explosion in Hiroshima was a tragedy in human history, which brought unimaginable pain and harm to innocent civilians. We should respect and cherish the memory of historical events, and at the same time strive to promote peaceful and friendly international relations and avoid similar tragedies from happening again.

Finally, as international students, we should respect local culture and values, abide by local laws and regulations, respect the rights and feelings of others, and be good citizens. In addition, we can improve our intercultural communication ability from the following aspects:

1. Learn the local language and culture: Learning the local language and culture can help us better understand the local people's way of thinking, values and codes of conduct, and help us communicate and understand more smoothly in cross-cultural communication.

2. Respect differences: Different cultural backgrounds will lead to differences in people's ways of thinking and codes of conduct. We need to respect these differences, understand and tolerate local behaviors and opinions, and avoid arbitrary judgments and criticisms of local culture and values.

3. Accept challenges and learning opportunities: Cross-cultural communication is a challenge and learning opportunity, which can help us broaden our horizons, enhance our self-confidence and improve our communication and problem-solving skills. Therefore, we need to dare to accept challenges and learning opportunities, actively participate in cross-cultural communication activities and improve our cross-cultural communication ability.
