Upon closer inspection, two people emerged from the wardrobe.
A man and a woman—these were her communications teachers.
Morse code is a must-learn, because she will be using it quite a lot.
Of course, Hou Qian had been exposed to it when she was still on the substitute team. Although she had forgotten most of it, she can still adapt to it after reviewing it a little.
These two teachers taught her to listen to Morse code on the radio.
Tell Hou Qian a frequency band and in what approximate time period to listen to the radio. External personnel will use the frequency of the interference signal to form Morse code "tick" and "click".
With practice, you'll be able to find the pattern.
If you hear crackling or hissing sounds, most people would assume the signal is bad and might try moving their location or antenna.
Although there may be brief interference, as long as you stay in front of the radio and hear regular frequencies, it means someone is contacting her.
The CIA is better than anyone else at using various communication methods, constantly coming up with new tricks.
They also prepared a lot of high-tech gadgets for Hou Qian, such as virtual photography and wireless eavesdropping devices that automatically record audio without requiring anyone to listen in.
There's also a monocular night vision goggle, the kind that uses a button battery, which can be used continuously for about two hours in the dark.
Aside from firearms, Hou Qian was taught how to use all other handy tools.
If Hou Qian had any information to release, they told her to transcribe it into a notebook or computer, save it on a floppy disk, put it in an envelope, write the address, affix a stamp, and drop it into the mailbox.
Of course, this is just one small tactic; there are many other ways to release information. She can choose the method that suits the situation.
Seven days later, Hou Qian's ex-husband's insurance payout arrived. A customer manager from a bank in the United States called her, asking if she needed help with her financial management, saying that the returns were higher than interest and that she could earn an extra tens of thousands of US dollars in investment profits each year.
Hou Qian doesn't understand finance and is also resistant to it. Her ex-husband used to work at a financial company, but the company went out of business.
After politely declining the offer, Hou Qian headed to the checkpoint to prepare to cross the border and head to Seattle.
By sheer coincidence, I encountered Sun Chenzhou at the checkpoint.
When Hou Qian received her passport, Sun Chenzhou was taken to the checkpoint to wait for her.
"Are you feeling any better?" Sun Chenzhou's first words to Hou Qian were words of concern.
Hou Qian almost broke down, her eyes welling with tears, and asked, "What are you doing here?"
“I’ve been here for quite a while now. I came here as soon as you had your accident, but my colleagues at the company said it wasn’t convenient for me to see you right now, so they didn’t let me come over,” Sun Chenzhou said.
These words alerted Hou Qian. As she racked her brains for a solution, she heard a voice in her ear: "Hello, Comrade Hou Qian, I am an employee of Da Mei Hai Na branch. General Manager Xing instructed me to escort you home!"
"Thank you." Hou Qian said nothing more, her face expressionless, perhaps still a little nervous, and she reached out to put her arm around Sun Chenzhou's arm.
Then Sun Chenzhou grabbed her hand and squeezed it hard a few times.
