THIRTEEN of the 28 new Hongkong members of the National People's Congress will be serving in the national legislature for the first time. Their nomination is expected to be endorsed in the course of the 12-day Guangdong People's Congress, which opened in Guangzhou yesterday. Aside from mainland officials, most of the neophytes are well-established businessmen and professionals with a pronounced ''patriotic'' record. Here are brief biographies of the 13 new Hongkong delegates to the national legislature. Mr Chan Wing-kee, managing director of Yangtse Kong Garments. Mr Chan strongly supports China's bid for unconditional renewal of Washington's Most Favoured Nation trading status.
