Among some 6 million science and technology person­nel, 31.1 percent are women. In some cases, science and technology personnel leave China because of job dislocation or working conditions. However, most of them are overseas Chinese who still have family members In other countries. Such phenomenonshould be regarded normal. On the other hand, many overseas Chinese science and technology personnel return to motherland to work. Basically, b·ralndraln has not been a problem.
