With the support of our readers, China Today has become successful in helping the world learn about China, and has built a bridge of friendship between the people of China and the rest of the world.
Every day we receive many letters from our readers expressing their admiration (赞赏,钦佩) for China and their suggestions for improving the quality of the magazine. Some letters are published in "Postbag" while others are kept for reference (参考).
Many readers have suggested contests (竞赛) to develop closer contact between readers and editors. We held a History and Tourism Contest in 1995 and a China Trivia Contest in 1996. We received warm responses to both.
This year, China Today is holding a Reading Contest. Questions, chosen from articles published this year, will appear every three issues. Entrants must mail their answers before January 31, 1999. Fifty entries with correct answers to all questions will be selected as prize winners. All winners will be named in the April 1999 issue.
