For more than a month after the meeting, Liu Manqing heard nothing further from the Dalai Lama. She gave a final warning, saying that, “if you continue to create difficulties after May 20, I will risk my life and return to Nanjing by way of India.” By May 19, she stated that she would leave Tibet alone, without any wula (corvée laborers), if she had not received the official document by May 25.
