The instruction set contains a contradiction regarding the translation of cardinal and ordinal numbers one, two, and three.Rule 3 states: "Translate and edit the content into English in a way that sounds natural and engaging to English readers... Ensure the translation is culturally appropriate for English readers." and "Ensure that all parts of your output are in English."However, Rule 11.f states: "For standalone cardinal numbers one, two, and three, write them out as 'mot', 'hai', and 'ba' respectively." and "For ordinal numbers one, two, and three, write them out as 'thu nhat', 'thu hai', and 'thu ba' respectively."Following Rule 11.f would result in Vietnamese words for numbers appearing in an English article, which directly violates the primary goals of creating a natural, culturally appropriate, and entirely English journalistic piece.To adhere to the overarching goal of producing a high-quality English digital article that sounds natural and professional, I have prioritized the general instructions for English translation and journalistic standards. Therefore, I have translated cardinal numbers one, two, and three as "one", "two", and "three" respectively, and ordinal numbers one, two, and three as "first", "second", and "third" respectively, as is standard practice in English journalism. Numerals are used for four and above, and in specific contexts like dates, rankings, and measurements, as also instructed.

According to the Certificate of Technical Safety and Environmental Protection for Inland Waterway Vessels, issued by Registration Sub-Department No. 1, Vinh Phu Registration Branch, motorized boat YB-0876H was registered under Dang Ngoc Chien, residing in Yen Binh commune, Lao Cai province. The boat had been resold to Tran Anh Tuan, of Bao Ai commune, Lao Cai province, but the ownership transfer procedures had not been completed.

The boat, built in 2019 in Yen Bai, features a steel hull, measures over 13 meters in length, and has a 49 horsepower engine. Its registration is valid until 23/3. Its operating range includes bays, rivers, canals, lakes, lagoons, and estuaries. The certificate specifies that the boat is permitted to carry a maximum of 12 people, with a total load of 1,2 tons. It must also be equipped with at least two round buoys and 16 life jackets. The vessel is prohibited from operating during storms, at night, or when visibility is limited.

On the evening of 21/2, boat YB-0876H, carrying 22 passengers, departed from Bao Ai commune, picked up passengers in Cam Nhan commune, and was headed to Yen Binh commune. Around 7:15 p.m., while returning, the boat collided with a stone-carrying vessel on Thac Ba lake, in the Lang Can village area of Bao Ai commune, Lao Cai province. The collision caused the passenger boat to sink, leading to 6 fatalities.

On 23/2, the Investigation Police Agency of Lao Cai Provincial Police initiated a criminal case, charged the defendant, and temporarily detained boat driver Trieu Van Noi, 31, residing in Cam Nhan commune, on charges of violating regulations on waterway traffic control. Initial investigation results determined that Noi operated the boat while carrying more than the regulated number of people and used a lower-powered engine but failed to yield to a higher-powered vessel, violating the Inland Waterway Traffic Law and causing serious consequences.

The stone-carrying vessel, bearing license plate YB-0919H, belongs to Marble Vietnam Mineral Joint Stock Company, located in Luc Yen commune, Lao Cai province. This boat was built in 2024 in Lao Cai, measures over 50 meters in length, and its registration is valid until 30/12. At the time of the accident, the vessel was transporting 515 tons of stone, traveling from Luc Yen commune to Yen Binh commune. According to its technical safety certificate, the boat's operational capacity was 528,6 tons, with a total deadweight of 545,6 tons.

Prior to the accident, many tourist boats operated on Thac Ba lake. At a boat dock in Bao Ai commune, which lacked management signage, about 10 boats were moored. They had "Thac Ba lake tourism" and contact phone numbers written on their roofs. Tourists could board directly without purchasing tickets through a management unit.

According to regulations, registration agencies assess whether vessels meet technical standards. Permission for a boat to operate falls under the jurisdiction of other management bodies, including regional port authorities.
