you already live in China? sounds like you did the hard part already

Unlike satanically racist USians, China bases its accusations of espionage on the work of its intelligence services rather than the color of your skin, so you should be fine

Just be normal, and interact with people normally, would ve my guess. Integrate into the community, how depends on your location and your interests. Just don't isolate yourself, it is unhealthy and contraproductive.

You're projecting extremely hard the brutality and racism of your own government onto the Chinese one

There is 0 evidence to suggest they would do this to you. The same absolutely cannot be said about America to both Chinese aliens and even their own Chinese citizens

As a Chinese person, my suggestion is:

There is no need to worry. If you sincerely help others, they will notice it.

1. Although I feel that China has the strength to defeat the US within the First Island Chain and has been preparing for war, I do not believe China will proactively initiate a war with the US. It is more likely to punish America's allies, causing America's security guarantees to fail, possibly targeting the Philippines.

2. If a direct conflict with the US does occur, continue with your usual activities, pay attention to official announcements, and express your aversion to all wars。Expressing regret for the loss of lives on both sides (do not appear happy when discussing a war, as this may provoke hostility from the public,). Do not act like a spy by obsessively inquiring about military matters, harming others, or deliberately deceiving others to gain an advantage for the US military.

3. Do not apply the precedent of the US placing Japanese-Americans in internment camps during World War II to China.
