Malo ena oyeretsera zinyalala ku Beijing ndi amodzi mwa malo omangidwa kuti athetse mavuto oyeretsera zinyalala mumzindawu ndi madera ozungulira. Anamalizidwa mwalamulo ndipo anayamba kugwiritsidwa ntchito mu June 2009. Pakadali pano, dera lapakati pa tawuniyi likugwiritsa ntchito njira yophatikizana yoyeretsera zinyalala popanda malo oyeretsera zinyalala. Zinyalala sizimatsukidwa ndikutayidwa mumtsinje kudzera mu payipi yosakanikirana yomwe ilipo, zomwe zimapangitsa kuti madzi omwe alipo aipitsidwe kwambiri. Chifukwa cha kufulumira kwa ntchito yomanga mizinda, chiwerengero cha anthu mumzindawu chikukula mofulumira, ndipo kuchuluka kwa zinyalala kukuwonjezeka tsiku ndi tsiku. Kuphatikiza apo, kuti titeteze magwero a madzi a mzindawu, monga gawo lofunika kwambiri la zomangamanga za mizinda, ndikofunikira kumanga malo oyeretsera zinyalala mumzindawu. Malo atsopano oyeretsera zinyalala adzamangidwa mozungulira malo oyeretsera zinyalala, ndipo madzi oyeretsera azigwiritsidwa ntchito ngati gwero la malo oyeretsera zinyalala kapena kutayidwa mumtsinje winawake.
