This affectionate letter touched many people, and Ren Zhengfei was also full of old tears.

"old tears" doesn't make sense.

In an interview, he said that he was psychologically prepared to "never meet his daughter in this life."

This old man has worked hard for most of his life, and at the age when he should have enjoyed his family happiness, he hasd to endure the pain of being separated from his daughter, which is really heartbreaking.

Meng Wanzhou, who is far away fromin Canada, also updated her situation in time, and sent a photo of her with her husband to report hershow she is safety.

In the photo, she is an innocent girl, happily holding her husband's arm, and naturally looking up at her husband's face.

"she is an innocent girl" - although possibly the correct translation, is a weird thing to say. Maybe she was smiling innocently?

Husband Liu Xiaozong also straightened up his chestback, and his eyes were gentle and determined, revealing the determination to protect his wife.

For posture we usually refer to one's back. But, perhaps he was puffing out his chest?

Seeing such photos, Ren Zhengfei can finally rest assured.

Or if you want to use "assured", I would combine the two sentences. "Seeing such photos, Ren Zhengfei can finally rest assured that his daughter is not alone."

Heris daughter is not alone.

She has a reliable husband to protect her from wind and rainany storm.

With "wind and rain" I think you are referencing a metaphorical storm. You could also say "to protect her through thick and thin".

We should consciously establish the consciousnessvirtue of hard work, cultivate the charactersistic of perseverance, and strive to cope with the unknown dangers calmly and achieve our life goals, just like Meng Wanzhou.

using the same word, or the same word with the same root (consciously and consciousness) so close together is regarded as bad style.

We can't be toolike "western politicians"; ignoring morality and law for our own interests and being cast aside as clowns.
