Wenxin Fan and Shen Lu, Fleeing China, Many Take Dangerous Route to US; Seeking opportunity, Chinese face risky trek through Latin America. Wall Street Journal, Apr 17, 2023, at page A1.
Note:
(a) "In China, a new hashtag—#zouxian, roughly translated as trek—started gaining popularity last year when some migrants posted footage of their journeys through Latin America on TikTok’s Chinese version, Douyin."
(i) cn.wsj.com: "在中国，一个新标签#走线（大意为长途跋涉）去年开始流行，当时一些移民在抖音(Douyin)上发布了他们穿越拉丁美洲之旅的视频片段。 抖音是TikTok在中国的姊妹版应用。"
(ii) There was no 走线 in Taiwan when I left there in 1984.
(b) "Mr Huang cut open the sole of his sneaker to retrieve two $100 bills that he had hidden. It was enough to take them to Necoclí, Colombia, by taxi, the last stop before the Darién Gap. Migrants prepared for the Darién crossing in Necoclí, shopping for tents, flashlights and water-purification pills. The passage through the Darién requires hiking along muddy paths in dense, roadless jungle for a couple of days or more, with little access to fresh water or defense against mosquitoes. * * * The Lis [father and son surnamed Li] and Mr Huang were among more than a dozen Chinese who started the hike through the [Gap] jungle. A rotten stench hovered over some sections of the trek"
