During the day, they moved forward, while at night, they stopped to rest. After five days, they roughly searched the first suspected location, which was already at the Huaxia and Vietnam border. They even encountered patrolling border personnel. Fortunately, they had evidence prepared in advance, and orders were issued from above, avoiding misunderstandings. Otherwise, with just the two of them acting like this, border guards might either capture them for questioning or open fire on the spot.
The search yielded nothing, so Li Yifei called Murong Yuanqing and others to report. Then he followed the border guards to the frontier station. After a brief rest, he and Xu Shanshan left to search in Vietnam, according to the plan discussed with Murong Yuanqing and others. Of the three locations, the suspicious point in Vietnam was the most probable. They originally searched the southern region first to avoid missing anything.
